We assume that the rework time and the rework cost increase linear with the time that a lot is held in stock … costs associated with switching between production and rework. For a given N, we derive an explicit expression for the …

This paper sets out to test the claim made in the lean production literature that the lean production system is universally applicable. The proponents of the lean production model insist that it will supersede both mass production and specialised batch production; but this paper argues that,...

Companies using production of small batches, with a large number of products made in a number of variants, often have a high level of work in progress. Much has been published recently about production flow groups and balancing of flow to solve the problems experienced in these companies and...

Describes a company‐based PhD project into the use of automated guided vehicles in a small‐batch manufacturing environment. The project led to a balanced‐cell methodology to facilitate the use of guided vehicles in a difficult environment. The methodology itself was found to provide...

Presents a mathematical model for determining Economic Production Quantity (EPQ) in a multistage flow‐shop production system for the case where the demand for items per unit time is deterministic and the planning horizon is finite. Solves an example problem to illustrate the model.

Discusses the variety of production control situations within process industries. Following a literature review, a typology is introduced which discriminates between two extreme types of process industries: batch/mix and process/flow businesses. Reviews the research in production and inventory...

Addresses the problem of implementing just‐in‐time (JIT) principles in a processing shop organized in a batch manufacturing environment. The focus is on a processing shop separated from an assembly shop by a parts store. Presents a multi‐criteria variant of the capacitated lot‐sizing...

Some hierarchical approaches for production planning in a batch type manufacturing environment are described. In a single stage production system, three aggregation levels exist: types, families and items. The performance of a hierarchical system model is largely dependent on the methods of...

The batch process is dominant in manufacturing activity. It is, therefore, to be expected that much effort is being put into improving its efficiency. At least as important as the type of advanced equipment now being installed is the organisation and management of the batch process. This article...

Much research has been reported on the possibilities of using various heuristic priority rules to sequence batches through a job shop. The SPT (Shortest Priority Time) heuristic, or modifications to it, has been proved useful in many studies. This paper reports on the results obtained when...
