In this paper, we consider more general and practical case of MWP–the constrained multi-source location problem (CMSLP), i.e., the location of multiple facilities with considering interactive transportation between facilities, locational constraints on facilities and the gauge for measuring distances. A variational inequality approach is contributed to solving the location subproblem called the constrained multi-facility location problem (CMFLP) in location phase, which leads to an efficient projection-type method. Then a new location-allocation algorithm is developed for CMSLP. Global convergence of the projection-type method as well as local convergence of new location-allocation algorithm are proved. The efficiency of proposed methods is verified by some preliminary numerical results.","PeriodicalId":55455,"journal":{"name":"Asia-Pacific Journal of Operational Research","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46588896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In real practice, such technologies have been implemented by firms, and they play an important role in increasing the operational efficiency of the firms as well as the whole supply chain through Operational Research (OR) methods. Thus, it is critical to consider the impacts of advanced technologies on supply chain management with OR applications. This special issue explores new practices and applications of technology-driven supply chain management in Industry 4.0. This editorial note summarizes the discussions on applications of different technologies in supply chains. Moreover, we list important future research directions based on contributed papers.","PeriodicalId":55455,"journal":{"name":"Asia-Pacific Journal of Operational Research","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46762634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assume that the gambler knows which horses have odds which are favourable to him, that he wants to bet in such a way as to have a given positive expectation of win on a race, and that he wishes to minimise the probability of loss of his finite capital. We show that the best strategy is to bet on all the horses whose odds are favourable so as to minimise the probability of loss on a race. We further show that in order to achieve the last objective it is advisable to have a bet on a horse with fair odds, and at times on a horse with unfavourable odds, in addition to a bet on a horse with favourable odds.","PeriodicalId":55455,"journal":{"name":"Asia-Pacific Journal of Operational Research","volume":"1 1","pages":"87-98"},"PeriodicalIF":1.4,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70433026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
