The development and implementation of a production planning and scheduling model in tyre manufacturing is presented. The objective is to simplify planning and scheduling, which is typically complex in tyre manufacturing. The procedure is divided into three parts: (1) the original problem is transformed into independent subproblems by considering the machine‐product compatibility matrix; (2) the production lots for each subproblem are determined by formulating each subproblem as a one‐machine capacitated dynamic lot‐sizing problem; (3) a heuristic algorithm is developed to determine the production sequence for each job on each machine.

The purpose of this article is to introduce techniques to plan and manage maintenance overhaul of power‐generating units. It is based on a case study conducted in a thermal power‐generating plant where bar‐chart scheduling was the planning method. The overhaul activity network was made up of many parallel networks and paths. This characteristic of the network allowed for greater flexibility in resource scheduling. Hence, it was possible to develop an efficient resource mix profile for the project. Special attention was given to “management by sub‐projects”, which would allow use of low memory computers. It was seen that management by sub‐projects yielded reasonably good results. Besides, sub‐project management was found to be very conducive to overall project control. Slippage charts were drawn at the rescheduling stage, and slippage could be identified to a sub‐project, then to the sub‐network and finally to the cause. This enabled the managers to halt project slippage.

The purpose of this article is to demonstrate the usefulness of a co‐ordinated control inventory model, when it is applied to a practical situation. A comparison is made between the costs incurred when a co‐ordinated replenishment policy is used with that of an independent control strategy. It is found that a substantial cost saving is achieved when a co‐ordinated control model is used, demonstrating that this model is superior to an independent control model.

The selection of part types for simultaneous processing in a Flexible Manufacturing System (FMS) is one of the most responsible phases of the short‐time production planning. The batching approach to part type selection is more popular in practice but this leads to the requirement for a preliminary evaluation of the results obtained. Using simulation is a convenient, no‐risk and cheapest way to do this, which is shown and discussed in the paper. The objective of batching approach is to maximize the number of part types in a batch taking into account constraints on tool magazine capacity and tool type availability. Two alternative ways of assigning weights in the objective function of the part type selection model are explored to direct the search to a different set of part types. A procedure to determine the mix ratios of the selected part types is used so as to balance the aggregate machine workloads. The model aggregations have been accounted for in a simulation experiment conducted to evaluate the performance of the batching approach and to investigate the sensitivity of total makespan and machine utilizations.

The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.

Outlines the specific characteristics of semiautomatic production lines which, in relative terms, are given less attention than other types of line. Suggests a methodology for balancing such lines, making comparison thereof with the traditional method of line balancing. Applies the method to a case which is a typical semiautomatic line.

This paper aims to evaluate how transformative learning is key to innovating sustainability education in the built environment in the region’s universities, in addition to reporting on the research project undertaken to integrate sustainability thinking and practice into engineering/built environment curricula in Asia-Pacific universities.
The project drew from the experiences of academics in built environment programmes and espoused a collaborative inquiry process wherein the role of the industry was vital. A literature review focusing on sustainability integration into curricula was followed by a workshop which brought together academic and industry participants.
The general direction of education for sustainability is moving increasingly towards integration and innovation. However, the slow progress of integration of sustainability in the built environment curricula may have been due in part to the outcome/practice-led approach of built environment education, which is the hallmark of the discipline and lends to a largely discipline-based curriculum framework.
The project focused only on the curricula of university programmes and courses taught in the participating Asia-Pacific universities and institutions.
This paper highlights how the framework for the proposed curriculum guide focusing primarily on built environment programmes and courses can provide guidance for potential application in other higher education institutions.
Much is written about embedding sustainability and education in built environment curricula. However, little analysis, application and collaborative work in Asia-Pacific universities have taken place. This paper considers the value of transformative learning in the innovation of the predominantly discipline-based engineering/built environment programmes for sustainability.
