TL;DR: A combination of analysis and simulation can be used to gain a far deeper understanding of the system dynamics than has so far been published, and it is shown that by better utilisation of the information flow, significant reductions in the demand amplification can be achieved without substantial expenditure.

TL;DR: A solution for the problem of the recording of product data and product-structure becomes a problem for the existing production/inventory control information systems in the form of the generic bill-of-material.

TL;DR: In this article, the authors consider simultaneous pricing and procurement decisions associated with a one-period pure inventory model under deterministic or probabilistic demand and investigate the necessary and sufficient conditions for an (σ, Σ) type policy to be optimal for the determination of the procurement quantity.

TL;DR: In this paper, a procedure for determining the optimal size and distribution of safety stocks in a general serial or divergent production/distribution process ruled by a base-stock control policy is presented.

TL;DR: An integrated production-inventory-distribution model incorporating many realistic conditions such as set-up time and cost, lead times, losses during production and distribution and recycling of production losses as well as backlogging is presented.

TL;DR: In this article, a hierarchical decomposition of multi-echelon production systems is proposed for serial and assembly systems, where each stage requires a fixed predetermined leadtime, and each stage is assumed to have a stochastic, stationary end-time demand process.

TL;DR: In this paper, the authors compared the performance of the Common Cycle, Basic Period and Extended Basic Period (EBP) approaches in the case of polypropylene film for packaging.

TL;DR: A review of the literature and the current research of the authors on MRP with uncertainty due to quality variations in the production process is discussed.

TL;DR: In this paper, a new heuristic algorithm has been developed and presented for minimizing the makespan criterion of a group scheduling problem based on the fact that jobs with higher mean total processing time should be given a higher priority in generating partial schedules that eventually lead to determining a complete schedule for the problem.

TL;DR: One model dealing with two cases of production configuration is developed for deciding the optimum number of kanbans between two adjacent workstations and is solved using a Markov Process approach.

TL;DR: In this paper, the potential gains of the OPT-and ABC-models were analyzed and it was shown that neither OPT nor ABC have a relevance to all product-mix decisions and their relevance is highly dependent on the time horizon and the manufacturing environment.

TL;DR: A “measure” is proposed that ranks different competing FMS designs according to their inherent flexibility as they relate to the maximum flexibility possible stipulated by the state-of-the-art.

TL;DR: In this article, the problem of minimizing the weighted sum of earliness and tardiness penalties on a single machine was considered and a simple and efficient lower bound was developed and several upper bounds were proposed.

TL;DR: A planning model for the assembly of new products, generally required in small quantities, and whose basic task times are relatively long, is presented, which was successfully implemented for on-line planning and scheduling of a new production line for theassembly of aircraft engine housings in which the plant had limited experience.

TL;DR: A description of the capabilities of the Decision Support System and the solution technique that is applied within the DSS for determining the required size and composition of the workforce is described.

TL;DR: In this article, the authors report and examine the most frequent occurring questions raised by organizations in their application and use of Statistical Process Control (SPC) in Western European automotive suppliers.

TL;DR: The applicability of multi-criterion approaches to the production scheduling problems of an FMS is explored and the pertinent literature on FMS scheduling involving multiple objectives is reviewed.

TL;DR: In this article, the acceleration of the distribution process can become an efficient solution which allows for optimal lot-sizes as well as for low holding costs, which is one of the most important challenges for the suppliers' planning capabilities.

TL;DR: The objective of the present paper is to develop a procedure to calculate relative operational performance ratings of a set of PUs using a data set from the recent literature, which involves twelve input and two output categories in a manufacturing setting.

TL;DR: In this paper, the authors present two important requirements for an economic evaluation of a project proposal for leadtime reduction, i.e., a team that analyses the consequences should represent a variety of business functions, e.g. marketing, production, logistics and engineering.

TL;DR: Delays time analysis is used to model the maintenance practices for coal face machinery within British Coal to predict the effectiveness of condition monitoring using the resultant downtime of machinery as the relevant measure.

TL;DR: In this paper, the problem of location choice for such production systems where the basic and additional location factors can be identified is considered and the set of all efficient solutions is found by the use of the PROMETHEE method which takes into account the above mentioned additional locations factors.

TL;DR: The positive linkages between quality and productivity are explored and types of joint improvement programs discussed, and the applicability of these concepts and methods to services is also considered.

TL;DR: This paper considers a scheduling problem in a stochastic single-product situation with production to order, and finds the best combination of rules for due-date setting to arriving jobs and production planning, by finding a rule leading to acceptable due-dates for most of the clients.

TL;DR: In this paper, a decision problem on nuclear waste managemnt, in while little information is available on the multiple criteria, representing each the point of view of a different actor: electricity producer, consumer, public body.

TL;DR: A hypothetical production system is simulated using different workers with different levels of personal factors when two different situational levels are present, and the results are compared to the traditional log curve and the impact on capacity planning is demonstrated.

TL;DR: This paper examines the throughput performance of the single/double carousel system in which a storage/retrieval machine performs pickup/discharge operations.

TL;DR: The state-of-the-art of part-presentation techniques for flexible part-feeding is reviewed and special attention has been placed on the use of computer vision techniques which has potentials in adding considerably to flexibility by simplifying grippers, component feeders, and location tooling, and by reducing engineering time required to implement it.

TL;DR: In this article Integrated Manufacturing System (IMS) is described as a procedure of product design, process design, implementation, and management, and the relation of CIM to SIS (strategic information system) is also mentioned, together with human-centered flexible manufacture.
