TL;DR: In this article, the authors extended the traditional economic production quantity model by accounting for imperfect quality items when using the EPQ/EOQ formulae, and considered the issue that poor-quality items are sold as a single batch by the end of the 100% screening process.

TL;DR: A stochastic management problem is reformulate as a highly e$cient robust optimization model capable of generating solutions that are progressively less sensitive to the data in the scenario set, and the method proposed herein to transform a robust model into a linear program only requires adding n#m variables.

TL;DR: In this paper, an inventory model for initial-stock-dependent consumption rate when a delay in payment is permissible is developed, where shortages are not allowed and the effect of the inflation rate, deterioration rate, and initial- stock dependent consumption rate and delay-in-payment are discussed.

TL;DR: The technique can be used to identify factors affecting performance and their relationships, structure them hierarchically, quantify the effect of the factors on performance, and express them quantitatively.

TL;DR: In this paper, the authors developed a retailer's model for optimal cycle and payment times for a retailer in a deteriorating-item inventory situation where a wholesaler allows a specified credit period to the retailer for payment without penalty.

TL;DR: In this article, the authors argue that an effective approach must be developed to support decisions on initiatives aimed at promoting customisation and preventing escalating costs and complexity in manufacturing, and propose a cost-effective solution for customised manufacturing is yet to emerge.

TL;DR: In this paper, the characteristics of ETO companies are described in terms of their markets, products and internal processes of their organization, set in the context of current trends in supply chain management.

TL;DR: In this paper, a simulation study indicates that the relative performance of the traditional workload control methods changes completely with for instance the presence or absence of a dominant flow direction in the shop.

TL;DR: In this article, a case study is presented to demonstrate the usefulness of an integrated approach to bridge the gap between internal quality improvement and external measures of customer needs and satisfaction, which is an important yet complex translation process.

TL;DR: In this paper, a study of self-assessment practices in 10 organisations was conducted by semi-structured interviews directed towards a range of issues related to the process, practice and management of selfassessment.

TL;DR: In this article, the relationship between quality certification, as indicated by the ISO 9001 and 9002 certificates, and the performance of Brazilian firms since 1992 is studied. But, as a rule, one cannot discern differential levels of performance across the two groups for different indicators.

TL;DR: An integrated approach for the automatic design of FMS is reported, which uses simulation and multi-criteria decision-making techniques.

TL;DR: The theory and procedures enable dynamic capacity planning to be carried out at the customer enquiry and order entry stages for versatile manufacturing make-to-order companies and give a general capacity planning method for other production planning methods.

TL;DR: Development of an optimal policy for the single-vendor single-buyer integrated production–inventory system to minimize the total joint annual costs incurred by the vendor and the buyer is dealt with.

TL;DR: This paper describes uncertainty using two types of demand scenarios; namely interval and discrete scenarios and shows that the corresponding models with discrete demand scenarios are NP -hard and that they are solvable by dynamic programming.

TL;DR: In this paper, the relative performance of just-in-time (JIT) and non-JIT plants operating in two distinct manufacturing industries: electronic components and auto-parts is analyzed.

TL;DR: The paper demonstrates that management's discretionary power over labor and overhead resources determines when the TOC and ABC lead to optimal product-mix decision and demonstrates that both the Toc and ABC may lead to a suboptimal product mix across a wide range of economic conditions.

TL;DR: A large bucket mixed integer programming (MIP) model is formulated which considers only efficient sequences and a tailor-made enumeration method of the branch-and-bound type solves problem instances optimally and efficiently.

TL;DR: This paper depicts the AMT selection process through an IDEF0 functional model that utilizes a combination of a cone-ratio data envelope analysis (CRDEA), which integrates decision-maker's preferences, and a new methodological extension in data envelopment analysis (DEA).

TL;DR: In this paper, the authors focus on facilitating an interface and collaboration among designer, buyer, and supplier at three planning horizons: strategic, tactical, and operational with respect to supplier relations.

TL;DR: In this paper, a branch-and-bound algorithm for the hybrid flow shop scheduling problem is proposed to minimize makespan, which can also cope with problems with release dates and tails.

TL;DR: Six new heuristics are presented to solve the scheduling of N jobs in a V-stage hybrid flow shop with identical parallel machines, when jobs are subject to precedence constraints, several time lags, and due-dates.

TL;DR: In this article, the authors focus on the results from two international surveys of academics and industrialists that indicate current practice and future intentions in this area and present a longitudinal case study.

TL;DR: The paper describes a procedure for optimising the performance of an industrially designed inventory control system using three classic control policies utilising sales, inventory and pipeline information to set the order rate so as to achieve a desired balance between capacity, demand and minimum associated stock level.

TL;DR: In this article, the authors extend the single-period problem to the case of multiple discounts with prices under the control of the newsboy or newsvendor, and develop algorithms for determining the optimal number of discounts under fixed discounting cost for a given order quantity and realization of demand.

TL;DR: In this paper, the authors presented the correct equation and numerical results for Eq. (10) and showed that the error only a!ects the optimum value of the order size.

TL;DR: In this article, the Banker, Charnes and Cooper (BCC) DEA efficiencies were introduced into an econometric estimate of a standard production function model, leading to a corrected factors version of the model, with significant improvement of the statistical explanation of the data.

TL;DR: It is found that the complexity of the experimental design problem remains constant (33 factorial design) when the number of machines increases, and an approximation of the optimal control policy is obtained.

TL;DR: A new approach combining the simulated annealing method for the cell formation and a branch-and-bound method forThe routing selection is presented, which aims to minimize the inter-cell traffic, respecting machine capacity constraints.

TL;DR: In this article, a binary encoding genetic algorithm and five specific genetic operators are designed to ensure that exploration takes place within the set of feasible solutions for the multi-level lot-sizing problem.
