... to standard time with 100 per cent performance level. Originality/value – Scheduling problems are complex and uncertain, and it is very rare for such systems to be exactly determined in all their complexity. According to grey systems theory, the job processing time can be considered as the object...

...Khairy A.H. Kobbacy; Sunil Vadera; Anna Ławrynowicz Purpose The purpose of this research is to improve efficiency of the traditional scheduling methods and explore a more effective approach to solving the scheduling problem in supply networks with genetic algorithms (GAs). Design/methodology...

... Manufacturing Simulation Scheduling Production scheduling deals with the way the resources of a manufacturing system (i.e. the workstations, personnel and support systems) are assigned over time to a set of activities so as to best meet a set of objectives. The fields of management science...

...Paolo Priore; David de la Fuente; Rau´l Pino; Javier Puente Dispatching rules are usually applied dynamically to schedule jobs in flexible manufacturing systems. Despite their frequent use, one of the drawbacks that they display is that the state the manufacturing system is in dictates the level...

... and scheduling reference models for industrial sectors where the MRPII paradigm is not appropriate. It outlines the process mapping approach adopted for data capture within the case study companies and the use of ARIS, Scheer’s enterprise modelling tool, for the production of sector reference models...

...Shiu Hong Choi; James Siu Lung Lee Minimising makespan aims to achieve high utilisation of equipment and resources by getting all jobs out quickly. This is an important scheduling criterion, especially for automated systems, because of the high investment cost. The problem, however, becomes complex...

...J.E. Spragg; G. Fozzard; D.J. Tyler The paper discusses the design, implementation and validation of FLEAS, a flowline environment for automated supervision of clothing manufacturing systems. The paper argues for a mixed initiative approach to system control which incorporates both a scheduling...

... systems such as theory of constraints (epitomised by OPT), just‐in‐time (JIT), etc. One key area for all manufacturing companies is the planning and control function. There is a wide range of generic proprietary software available that aims to meet a company’s planning and scheduling requirements...

...Chwen‐Tzeng Su Real time control and scheduling systems determine the vehicle routing plan based on the current status of the system. The status of a system can be represented by different attributes of demand such as location, quantity, and due date. The objective of this article is to propose...

... elements” is presented as well as a mathematical basis of calculating the manufacturing system flexibility using the resource elements. Simulations are used to examine manufacturing system performance and compare resource element‐based scheduling with conventional machine‐based approaches. The results show...

...S.H. Choi; J.S.L. Lee The pair‐wise comparison technique has been applied to many algorithms for solving complicated scheduling problems. The optimality gap between the pair‐wise comparison technique and mathematical programming model is mainly due to deterioration in performance when optimal pairs...

... performance of a flexible manufacturing system (FMS). JGL works, instead, as a dynamic rule for real time scheduling of FMS, defining a part releasing policy able to guarantee the reaching of a periodic steady state without non‐productive times on the bottleneck workstation. However, JGL does not assure...

... with global variables and global relations to achieve a design automation. Results obtained from design automation are transmitted to update the design model and the associative manufacturing model. In addition, scheduling and control are also integrated in the system. Distinguishes three scheduling levels...

...Tan Hock Soon; Robert de Souza School In recent years, many firms have rediscovered the importance of scheduling on the shopfloor. Within the manufacturing functions, scheduling remains among the most important and challenging tasks that must be performed routinely. Developing a schedule involves...

...Keith Porter; David Little; John Kenworthy; Peter Jarvis Investigates the efficiency of finite capacity scheduling tools within companies which employ them. Presents research findings of the Liverpool STS Research Group into “best practice” in short‐term scheduling. Concludes with a list of key...

...Molu Olumolade; Douglas Norrie An intelligent decision‐support system was designed for assessing schedulability prior to assigning parts for scheduling. This was designed as part of a larger system for intelligent, real‐time control of a manufacturing system operation, where one of the system...

...Pacifico Marcello Pelagagge; Gino Cardarelli FMS real time scheduling requires the concurrent solution of both loading and despatching problems. The loading strategy is the most critical and important scheduling decision in an FMS. Presents an effective loading rule (job‐group loading rule), based...

...Behrokh Khoshnevis; Geza Bottlik; Ali Reza Azmandian Assembly planning and scheduling are two major functions in circuit board manufacturing. Currently, assembly plans are developed in the absence of information about the state of the shop floor at the execution time of the assembly operation...
