Furthermore, due to the importance of inventory and capital investment in today’s fuzzy marketing environments, researches in fuzzy collaborative inventory models have become very popular research in recent decades. Therefore, in our integrated model with deteriorating inventory replenishment policy, we construct the crisp/fuzzy models with inventory investment constraints with fuzzy environments. Two different fuzzy decision-making methods are used to formulate the models. Convex fuzzy programming (CFP) method is used to maximize the weighted sum for each achievement level of the joint cost and constraints. An inverse weighted fuzzy non-linear programming (IWFNLP) is then proposed to satisfy the decision-maker’s desirable achievement level of service. A heuristic algorithm with mixed-integer hybrid differential evolution (MIHDE) is developed to solve the crisp/fuzzy models. Numerical examples and sensitivity analysis are developed to investigate the effectiveness of the proposed method in the fuzzy environment. From the numerical analysis, it can be seen that the IWFNLP method is a more efficient decision-making tool than the CFP method.","PeriodicalId":13645,"journal":{"name":"Infor","volume":"19 1","pages":"667 - 691"},"PeriodicalIF":1.3,"publicationDate":"2019-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80246859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To mark this important milestone and to highlight progress in Canadian Operational Research work, recent winners of the prestigious CORS Award of Merit were invited to contribute papers to a special issue. The Award of Merit is presented to a current or past member of CORS who made significant contributions to the theory, practice, training, service and promotion of Operational Research. Three papers were finally accepted. The first is by 2017 Merit award winner John Chinneck from Carleton University. His paper, titled “The Maximum Feasible Subset Problem (maxFS) and Applications”, provides a survey of the maximum feasible subset problem and its rich applications and solution methodologies. The second is by 2015 Merit award winner Tamas Terlaky from Lehigh University. His paper, titled “Examples with Decreasing Largest Inscribed Ball for Deterministic Rescaling Algorithms”, is an indicative highlight of his lifelong theoretical contributions to continuous optimization. The third is by 2009 Merit award winner and 2002 CORS president Dave Martell from the University of Toronto. His paper, titled “The use of aircraft tracking GPS data to develop models of the use of airtankers in forest fire”, which develops queueing models for airtanker deployment is a testimony of the tremendous contributions he made to the development of Operational Research tools for forest fire management. We thank the contributors for answering the call and the anonymous referees for reviewing the work. The special issue is a reflection of the quality work done by CORS members and a celebration of CORS.","PeriodicalId":13645,"journal":{"name":"Infor","volume":"1 1","pages":"495 - 495"},"PeriodicalIF":1.3,"publicationDate":"2019-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80731123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assume an imperfect production process with a known of defective probability. The buyer conducts a 100% quality check. However, due to an imperfect inspection process, the quality-controller may reject a good item as a defective item (Type I error), or accept a defective item as a non-defective item (Type II error). Different from existing research, we incorporate freight cost (a function of shipping weight and the distance between the vendor and the buyer) and stochastic lead time (a function of production and transportation times). The objective of the study is to minimize the joint total expected cost. This study indicates that Type I error is more significant when it is compared with Type II error. We also illustrate how the joint total expected cost and the lead time are significantly influenced by the distance of the buyer and the vendor. The results of our analysis also show that lead time can be shortened if the vendors speed up their shipment with smaller production lot sizes. Numerical examples and sensitivity analysis are given to illustrate the results.","PeriodicalId":13645,"journal":{"name":"Infor","volume":"25 1","pages":"597 - 622"},"PeriodicalIF":1.3,"publicationDate":"2019-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86638105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These features are rarely jointly considered in the related literature, but commonly found in real-world applications. The models properly represent the problem in this industrial sector and can be used as a tool to support production and distribution planning in small companies. A large set of random and realistic instances is used to contrast the performance of the models in terms of both solution quality and computational effort. It is shown how much integrating production and distribution decisions in a single framework helps to reduce the total cost of the system, in comparison with a sequential approach that follows a common practice in this industry. This cost reduction comes at a higher computational effort, though.","PeriodicalId":13645,"journal":{"name":"Infor","volume":"340 1","pages":"563 - 596"},"PeriodicalIF":1.3,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80751338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
