Abstract

The Global Manufacturing Research Group (GMRG) is an informal group of researchers conducting operations management research throughout the world. Describes aspects of their survey research on manufacturing practices. Presents the background of the project, a bit about the group itself, and specifics on getting involved in the group. Presents the principles which guided the first and second rounds of the GMRG global survey and the theory underlying their survey instrument and its revision. Finally, provides several details of the research methodology and some of the research findings.

Abstract

A very important concern of physical distribution managers is deciding the location of warehouses (distribution centres or depots). It is, therefore, not surprising that this location problem has been receiving considerable research attention and indeed, some impact has been made in actual industrial warehouse location decisions. The interested reader is referred to the expository articles, which describe both the theoretical developments and some practical applications of the theory.

Abstract

The problem considered in this paper is that of determining the order in which customers will be visited by delivery/pick‐up vehicles. Typical examples of this problem are the routing questions faced by the Post Office in making local deliveries, industrial laundry service companies and garbage collection agencies. Generally, in these situations, the vehicle leaves a central facility, visits a known set of customers and must return to the central facility before a specified amount of time has elapsed (e.g., a shift). In addition to these characteristics, it will be assumed that there is sufficient capacity on each vehicle for its delivery or pick‐up requirements during the available time and the customers are indifferent as to when the vehicle arrives during this time. The problem is to assign customers to routes for individual vehicles so as to minimize the total travel time for all vehicles, without having any vehicle exceed the amount of time available.

Abstract

ABC analysis is used to sort inventory into categories which determine how much attention they will be given. But it is of wider management application and can be extended to cope with more than one classification criterion.

Abstract

Asks whether China will be able to sustain its current rate of economic growth and compete in the North American market, by comparing manufacturing practices in China and North America. Uses data obtained by questionnaire from companies in the non‐fashion textile and small machine‐tool industries. Considers three factors that differentiate the two regions: asset management, market responsiveness, and manufacturing management. Concludes that the differences are substantial and that it is unlikely that China will penetrate the markets of industrialised countries.

Abstract

Prioritising items for management attention has been advocated in operations management for a long time, normally using ABC analysis (inventory control). This focuses attention on the “A” category items to maximise managerial effectiveness. Empirical evidence shows that this is a reasonable rule for allocating scarce resource‐management time but presents difficulties when the manager has to take more than one important dimension of a situation into account. A joint criteria matrix is put forward within the ABC framework and an industrial application given. The joint criteria matrix has practical utility provided ranking on some scale of measurement is realistic. The appropriate number of categories must be defined by the user. Combining criteria will probably require different analytical approaches, e.g. goal programming or heuristic approaches. Utilisation of the matrix by managers can provide an explicit method for taking a range of criteria into account in the development of inventory policies.

Abstract

Over the last few years, several international studies have independently shown a significant correlation between the number and intensity of manufacturing practices in use and the performance of a firm. The conclusion is an unsettling: “the more the better.” This paper uses the Global Manufacturing Research Group’s (GMRG) second round database to deepen our understanding of this relationship. The shape of a scatterplot of practices versus performance resembles the shape of an American or rugby football and is often called the “performance football”. The performance football seems to be a general phenomenon so, as practices are added, a firm should garner earlier performance improvements if it followed the upper edge of the performance envelope. This is consistent with the “sandcone” model or sequential capability building model that suggests that a firm should first invest in quality practices and then add others over this base. We first demonstrate the relationship between practices and performance holds for the GMRG data and then we make detailed comparisons of the firms along the upper and lower edges of the football. The comparisons provide some evidence that there is a sandcone effect.

Abstract

Describes the design and implementation of an incentive scheme for two different groups of computer operators in a large Middle Eastern electricity and distribution company. Compares computer outputs from each group and suggests that performance is dependent not only on the kind of work processed, but also on the effort of workers. Concludes that through proper application of work measurement and by enlisting the capabilities of the computer itself, successful incentives can be achieved.

Abstract

Purpose

Owing to the manufacturing trend of stringent product disposal regulations, a new business scenario, which requires an alternative disposal option on consumer products and further product recovery operations, is increasingly important for promoting sustainable supply chain performance. The purpose of this paper is to explore the use to post‐use stage of the product lifecycle, that may have significant potential for increasing product utilisation value and reducing product disposal to landfills.

Design/methodology/approach

The paper proposes a re‐classification of the 6R (reduce, recover, redesign, reuse, recycle, remanufacturing) methodology for rectifying waste minimisation along a supply chain, to increase product utilisation at the post‐use stage.

Findings

Intensive study of 6R considerations to improve end‐of‐life planning and strategy and extend of product lifecycle management is lacking. None of the existing supply chain frameworks clearly illustrates the aspects of 6R perspectives for the use to post‐use stage.

Research limitations/implications

The main limitation is that this study only focuses on 6R perspective for achieving waste minimisation along a supply chain. There is a need to explore various practical issues of the implementation, including the establishment of specific performance metrics for various manufacturing industries to assess organisational performance.

Practical implications

This proposed sustainable supply chain for collaborative manufacturing may provide a very useful source of what needs to be implemented and achieved to meet the requirements of sustainability, which is the current and future trend of manufacturing.

Originality/value

This paper provides some of the insights into holistic aspects of 6R perspective to increase product utilisation value between use and post‐use stages.
