Project Title:	Development of a Decision Support System for the Improvement of Air-cargo Containers Loading Efficiency with the objective of minimising cost
Investigator(s):	Chan FTS
Department:	Industrial & Mfg Sys Engg
Source(s) of Funding:	Small Project Funding
Start Date:	12/2005

Abstract:

Objectives: The aspiration of the project is to develop a practically implementable methodology for optimising the Air-cargo containers loading plan to minimise the freight cost under resource constraints. The specific objectives to be accomplished through this project encompass: (i) To develop the quantitative model for selecting the optimum number and type of air-cargo containers to provide minimum freight cost from a given cargo lot and available containers. (ii) To develop a heuristic to optimise the filling of selected containers and accordingly provide the loading plan for each cargo box. Loading plan for each cargo box will have the name of container to which it will be loaded and the associated location inside the container for minimisation of freight-cost. (iii) To ensure that the critical parameters, such as different sizes and shapes of the containers, their pivot weight, volume, pivot cost, etc. are considered in modelling. (iv) To ensure that decision-maker can do “what-if” analysis to evaluate the different alternatives and promotions / packages offered by the air-lines at the last minute. (v) The combined module should be able to structure an “expert system” for optimisation of air-cargo loading problem. (vi) The underline objective of this methodology will be to have an approach that can be practically implemented and air-cargo loading practitioners should be able to use it. (vii) Methodology can be converted in the form of user-interfaced software. Problem formulation: Air-cargo loading problem can be briefly formed/stated in three steps as follows: (i) Selection of optimum number of containers from the available containers to minimise the cost, considering the different volumes, pivot weight capacities, pivot costs, extra weight or under weight penalty costs of available types of containers. The lower bound for the minimum freight cost can be calculated with consideration of primary constraints. (ii) Allocation of cargoes with same code number to a container with consideration of pivot weight and volume of container. (iii) Generation of optimized loading plan for each cargo box such that all the primary and secondary constraints are satisfied.

Investigator(s):	Chan PLY
Department:	Industrial & Mfg Sys Engg
Source(s) of Funding:	Competitive Earmarked Research Grants (CERG)
Start Date:	12/2006

Abstract:

(1) Establish statistical and analytical models for the sensors used in condition-based maintenance that are not 100% accurate. (The models will be used to determine the robust optimum threshold against the effect of inaccurate sensor inputs. This is important because in the literature, most authors assume that sensors are 100% error free, which is obviously not a realistic assumption.) (2) Establish decision making models for a common practice in which data recorded from sensors are observed periodically but not continuously. (Even though sensors record signals continuously, however, for operational reason the data received from sensors are not always analyzed continuously but very often analyzed at regular time intervals. There is a need to develop decision rules based on this scenario. To minimize system downtimes and costs, the threshold and action plans need to be determined appropriately.) (3) Establish models for imperfect inspection which may give wrong indication of the state of the system. (This will balance the probability of making wrong decisions to maintain the system unnecessarily (Type I error) and not to maintain the system when such maintenance is needed (Type II error), with the objective of maximizing the system availability or minimizing the cost under constraints on Type I and II errors.) (4) Establish models for imperfect maintenance and replacement, where the system will not be as-good-as-new after maintenance or replacement. (This research will be based on the assumptions in items 1 and 2, in the presence of sensor error and analysis of sensor data at regular time intervals.) (5) Set different grades for inspection, maintenance and replacement according to the age of the system, and thus optimize the resources required for such actions. (An old system may be very costly to maintain, despite it shorter expected residual life. From an economical point of view, setting different grades for inspection, maintenance and replacement is therefore desirable.) In fact, this practice is commonly adopted in the industry according to rules of the thumb without much theoretical analysis. (6) Establish models for items 3, 4 and 5, assuming that system degradation is a continuous process, which is more realistic and mathematically more accurate than the finite state assumption. (7) Develop optimum maintenance strategies using cost as the objective for the optimization of the maintenance plans, assuming that the maintenance cost (1) is higher for older systems, and (2) depends on the severity of the system damag. Develop optimum maintenance strategies using both short-run availability and average availability of the system as the objective function in optimizing maintenance plans.

Project Title:	A multi-material virtual prototyping system for functionally graded objects
Investigator(s):	Choi SH
Department:	Industrial & Mfg Sys Engg
Source(s) of Funding:	Small Project Funding
Start Date:	12/2006

Abstract:

This project aims to develop a multi-material virtual prototyping system for layered manufacturing of functionally graded (FGM) prototypes to facilitate advanced product development and biomedical engineering.FGM objects are made of materials with composition gradients that change gradually from one to another. They possess better properties for severe operating conditions than that of single-material, and they are particularly useful as tissue scaffolds for repairing damaged human organs. It would therefore be desirable to develop multi-material layered manufacturing (MMLM) technology for fabrication of such objects.The proposed system addresses a key software issue of MMLM technology, and it may be adapted for intelligent control of practical and viable MMLM machines for fabrication of complex multi-material objects.The proposed system consists mainly of a representation scheme for modelling FGM objects, which will be subsequently integrated with a topological hierarchy-based toolpath planning algorithm to form the proposed virtual prototyping system for digital fabrication and analyses of complex multi-material prototypes. With such prototypes, the designer can analyse the product designs thoroughly, while the surgeon can study the operations in detail. The prototypes may also be transmitted over the Internet to facilitate collaborative product development and collaborative medical consultation. Hence, product development cost and lead-time can be reduced considerably and surgical operation quality and success rate can be enhanced substantially.

Project Title:	Values of real-time information visibility in RFID-based supply chains
Investigator(s):	Huang GQ
Department:	Industrial & Mfg Sys Engg
Source(s) of Funding:	Small Project Funding
Start Date:	01/2006

Abstract:

BACKGROUND AND MOTIVATION It has been commonly accepted that the supply chain must be coordinated to share production information to optimise the performance of the entire supply chain and individual enterprises involved in the supply chain. However, previous research into supply chain dynamics and concurrent engineering has mainly concentrated on highlighting the importance of information sharing on individual basis without providing concrete guidelines on what information to share and how to share them. The applicant has recently led a major research into the impacts of sharing information on the supply chain dynamics. A number of research papers have been produced and published in some reputable journals such as International Journal of Production Research and IEEE Transactions on SMC. Major developments in Radio Frequency Identification (RFID or Auto-ID) technology have recently taken place in supply chain practices. RFID has provided new opportunities and new ways of sharing and showing information on a real-time basis. Such real-time information sharing and visibility also impose new challenges for supply chain decisions and operations. OBJECTIVES The purpose of this proposed research is to investigate the values of real-time information sharing and visibility on the supply chain dynamic performance within an advanced supply chain environment where enterprises and the supply chain are well equipped with the emerging RFID, with an intention to provide practical guidelines to the design and development of the supply chain and associated decision models. More specifically, the following objectives will be investigated: (1) To develop a supply chain dynamic performance measurement system which clarifies the variety of the supply chain structures, identifies the key dynamic performance indicators, key production information, main modes of sharing information, and appropriate performance models to link these factors. (2) To formulate decision models for the supply chain and its constituent enterprises under typical schemes of deploying the RFID devices (readers and tags). (3) To design and carry out a series of experimental simulations using the proposed decision models under various settings as determined by typical factors (e.g. sharing modes, level of visibility, etc). (4) To analyse the experimental results and draw implications on the design of RFID-based supply chain and associated decision support systems. KEY RESEARCH ISSUES Some of the major research questions that will be addressed in this project are selected and listed as follows: (1) How to deploy RFID devices including readers and tags in a typical supply chain consisting of upstream manufacturers, distribution centers / warehouses, relailer shops and consumers? (2) What information should be made visible and shareable through RFID? (3) How (to what extent) supply chain enterprises should share the information? (4) What are the major motives and barriers (concerns) for individual enterprises to take advantage of RFID to share production information in the supply chain? (5) How does real-time information and visbility affect the supply chain operations and decision makiong? (6) In what mode (way) should individual enterprises in the supply chain share real-time production information?

Project Title:	A Generalized Change Detection Framework
Investigator(s):	Lau HYK
Department:	Industrial & Mfg Sys Engg
Source(s) of Funding:	Small Project Funding
Start Date:	09/2005

Abstract:

In essence, an intelligent change detection framework is capable of adapting itself to changing functional requirements and environmental conditions, and be able to identify and characterize changes with reference to some defined situations. Such a framework would form the core of automated systems that require the detection of changes over a finite time frame. Systems such as real-time tracking systems for automated material handling, cargo terminals, warehouses, airports; security monitoring systems for intruder detection, car park security control; transportation system for monitoring traffic flow control and accident alert; and health care systems for monitoring of patients or individual required close attention. Current research and development in monitoring and change detection methodologies are mostly based on a centralized architecture where the entire system is self-contained and tightly integrated. Despite its benefit of simplicity and manageability, such a configuration with a single threaded algorithm that executes on a computation node is inflexible and lack of scalability. Moreover, with dependency of a single computation node, the performance is limited by the resources of the computation node. What is worse is that, such a scheme is vulnerable to system failures as there is no back up resources designed for fault tolerance. These limitations of most conventional approaches therefore motivate the development of a decentralized change detection framework that provides improved adaptability to different configurations, scalability as requirement expands, and fault tolerance as the framework incorporates backup computation resources. More specifically, the proposed research aims to develop the algorithms that form the basis of the generalized change detection framework that is based on the general suppression control framework (GSCF) that has been researched by the investigator [ ]. GSCF was originally conceptualized for the control of modular self-reconfigurable robots (MSR), and its development was inspired from the biological immune system. The key objective of this project is to generalize the GSCF through the (1) formalization of the action stimulation and suppression mechanisms that are incorporated in GSCF, and (2) investigation in the context of generic change detection.

Abstract:

(1) Main purposes, key issues amd problems addressed] The development of a framework that provides a formalism for system specification, a mechanism for understanding the interactions of components, and a tool for building an implementation will significantly facilitate the methodical development of highly effective cooperative control systems in automation. A cooperative control system in essence consists of multiple, autonomous components that interact to control their environment with the performance of internal and observable actions. Typical automation systems that benefit from effective cooperative control include robotic production systems, automated warehouses and distribution centers and terminals and transportation systems. One of the prime aims of a cooperative control scheme is to effectively coordinate and support group activities.(2) The achievement of this control paradigm would represent a major advancement in the field of cooperative system control, and would be warmly welcomed by many local industries that rely on automation as an integral part of their businesses. Hong Kong is one of the largest logistics centers in the world, and express cargo hubs, airports, port container terminals, and manufacturing operations deploying various kinds of automated equipment to enhance operational efficiency will benefit from the outcomes of this study. This study will focus on the introduction of a novel approach to the modeling and analysis of cooperative control systems, based on the general suppression control framework (GSCF) developed by the investigator. GSCF was originally conceptualized for the control of homogeneous autonomous agents by using the solutions of the artificial immune system (AIS), whose development was inspired by the biological immune system.(3) The key objective of this project is to develop a generalized framework based on GSCF for the behavioral modeling of cooperative systems in the automation domain through (1) derivation of the generic building blocks (known as suppression units) for modeling cooperative components, and (2) formalization of stimulation and suppression algorithms for the computation of the actions performed by these abstract cooperative component models under some defined constraints. With the ultimate goals of delivering superior cooperative control systems, the proposed framework will impart a systematic methodology for cooperative system modeling and evaluation, and produce a system design with desirable characteristics that include seamless connectivity, flexible scalability, and robustness.(4) [Main objectives] Specifically, the project will seek to achieve the following objectives: I. To generalize the theory of GSCF for modeling heterogeneous components (in terms of generic building blocks introduced in this research) within the domain of automation. II. To develop algorithms defining the mechanism for determining the activities of the components in a cooperative control system, and evaluation of the overall behavior of the system. III. To investigate through detailed simulations and experimentation with laboratory-scale setups the properties and performance of typical cooperative systems that are modeled with the generalized GSCF framework.

Project Title:	Web-Based decision support system for polishing process optimization
Investigator(s):	Lo VHY, Huang GQ
Department:	Industrial & Mfg Sys Engg
Source(s) of Funding:	Small Project Funding
Start Date:	01/2006

Abstract:

BACKGROUND Polishing adds considerable value to many products manufactured in Hong Kong. At present the determination of polishing quality standards is often a subjective process which does not optimize the relationship between quality, value added, and production costs. This often results in products of inferior quality, and a failure to exploit new materials, products and equipment. OBJECTIVES The aim of this project is to develop a systematic Decision Support System for the polishing industry through innovative uses of polishing technologies and scientific decision-making. The project has four specific objectives: 1. To establish a data mining methodology for analyzing polishing data (both lab experimental and field data) to extract polishing knowledge and rules. 2. To research and establish a decision model for polishing process optimization using the polishing rules and data. 3. To design and develop a web-based decision support system that incorporates the data mining and process optimization models developed in the first two objectives. 4. To test, verify and adjust the model and system. RESEARCH ISSUES Key research issues / questions related to the first 3 objectives are listed as follows. Key research issues of designing the data mining algorithm includes: • How to effectively represent a fuzzy rule including fuzzy variables and their membership functions by a chromosome in evolutionary algorithm? • How to improve the efficiency of the data mining process on a large set of polishing data? • How to design effective genetic operators, like crossover and mutation, to search good rules? • How to measure the usefulness and accuracy of the rule which consists of multiple consequences? The following are the key research issues in designing the process optimization algorithm: • How to handle multiple objectives? • How to represent the multi-stage characteristic of the polishing process? • How to represent and operate on fuzzy decision variables? • How to evaluate a fuzzy rule? Research issues related to the design and development of web-based systems include: • The system must serve multiple user groups, including polishing technology providers and consumers, polishing data providers, process analysts, etc. • The user interfaces of the system client components should reflect the good practices? • The system would be based on web service standards for scalability.

Investigator(s):	Yiu CKF, Mak KL
Department:	Industrial & Mfg Sys Engg
Source(s) of Funding:	Seed Funding Programme for Basic Research
Start Date:	02/2006

Abstract:

Since most voice recognition devices are based on the hidden Markov chain and are trained with fairly clean signals, their performance usually deteriorate significantly in a noisy environment. Conventional design of hands-free communications system often concentrate on the noise reduction and the distortion of signal, but the trade-off between distortion and noise reduction and the optimization of the final recognition accuracy has not been explored properly. We propose to investigate this problem here. In order to increase the recognition accuracy, there are several fundamental problems we need to overcome. Our main objectives are the following: i) The first problem is to minimize the echoes. The acoustic echoes stem from the acoustic coupling between the loudspeaker and the microphone. Adaptive filters in a closed-loop path are often employed to identify the echo path and to cancel the echo. In the situation where a user wants to issue a command while the device is talking, it resembles the moment of double-talk where the microphone will pick up both the command and the speech of the device. The acoustic echo canceller therefore needs to be able to operate under double-talk situations and provide fast tracking of echo path variations. In the literature, most echo cancellers rely on the use of a double-talk detector to retain robustness. However, it fails to indicate the presence of double-talking for a time period after double-talking begins. Another technique is to employ a two-path model with a fixed foreground filter and an adaptive background filter. It has the advantage that double-talk detectors are not required. But this configuration cannot handle cases such as double-talks occur closely in time with echo path variations. In this part of the project, our main concern is the design of a robust echo canceller with fast tracking of echo path variations. The robust statistics technique will be employed so that the filters are adapted optimally under some kind of robust functions. Moreover, new multi-path configurations by combining more than one adaptive filter working in parallel will be investigated to increase the speed of tracking. We expect that we will come up with new novel designs of echo cancellers which are robust against double-talks and very efficient for tracking variations in this study. We will then optimize on the recognition accuracy with respect to the length of the adaptive filters and the signal to echo ratio. ii) The second problem is to look at noise reduction. The disturbance can be largely classified as convolutive and additive. The former refers to disturbance related to the acoustic environment. Additive disturbance is the background noise, “babble” from other speakers and also directional sources such as hands-free speakers. Most methods assume the noise is stationary, which is not true in practice. However, it is possible to tackle the problem with the use of sophisticated beamforming techniques. In this part of the project, we aim to develop better beamformers by optimizing on the recognition accuracy. Post-filtering techniques will be studied to further enhance the signal by eliminating diffused noise. In the noise reduction process, if time permits, we will also investigate the speeding up of the processing rate of signals. This relies on the use of a multi-rate processing system which analyses the signal into sub-band representation, process in the reduced subspaces and then syntheses back into its original full-band form. This has been a widely adopted technique for speech processing. The DFT filter banks are commonly used for efficient realization of the analysis and synthesis filter banks. However, sub-band processing introduces signal degradations, such as signal distortions and aliasing effects. Without a careful control of these adverse effects, the performance of the filter banks will be seriously affected. In this part of the project, we aim to develop novel techniques for the design of filter banks which will achieve pre-defined design requirements. Different measures of the filter banks, such as signal distortion, inband and residual aliasing effect and signal delay will be studied. Each design will be examined carefully to balance the performance against computational efficiency.
