In this paper, we develop a new pull type ordering system, based on the concepts of just-in-time production systems, which incorporates a backorder function which modifies the back-log carried over from the last period, and includes two types of buffer capacities, that is, safety stock and emergency delivery for the ICKDPS. By trading off these two types of buffer capacities, we develop a way of determining an economical safety stock level and emergency delivery rate which will assure system performance reliability to any pre-determined level.</p></div>","PeriodicalId":100476,"journal":{"name":"Engineering Costs and Production Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0167-188X(90)90097-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77804285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In these models we use optimal control theory to describe the time paths of resource use and production rate. The analytic solution for the most general specification of the model is unknown, however the imposition of a restriction on the relation between production rate and experience rate leads to a straightforward solution. The model implies that there exists an optimal trade-off between learning and production rate during the life of a program and that production rate should be changing throughout the life of the program in order to minimize cost. The model is compared with the learning curve, and the applicability of the model is explored by performing various parametric sensitivity analyses. The model's behavior is consistent with the dynamics of actual made-to-order production programs.</p></div>","PeriodicalId":100476,"journal":{"name":"Engineering Costs and Production Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0167-188X(90)90003-Z","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87188678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
