By introducing a leasing model, the optimal production decision of supply chain is analysed in case of considering expected rents. For the case of considering the expected rent, the risk-averse farmer's production decision-making problem is discussed by introducing conditional value-at-risk (CVaR) and the conclusion is drawn that when facing the lower labour costs of agricultural products, the farmer can effectively avoid risks by using rental model under the 'company + peasant household'.","PeriodicalId":113309,"journal":{"name":"International Journal of Inventory Research","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124342097","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}

The life time of an item and the lead time of reorder are exponentially distributed. Demands that occur during stock out period or busy period either enter an orbit of size N or are lost. The orbital demands compete their service with an exponential rate depending on the number of demands in the orbit. The waiting demands in the orbit may renege the system after an exponentially distributed amount of time. The server takes multiple working vacations at zero inventory. The steady state joint probability distribution of the number of customers in the orbit and the inventory level is obtained. Various performance measures and cost analysis are shown with numerical results.","PeriodicalId":113309,"journal":{"name":"International Journal of Inventory Research","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122534550","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 this article, we investigate the fashion designer's optimal pricing and production decisions, and product category management by incorporating the scarcity effect and the product variety benefit. We find that the popularity of the designer is very crucial in this problem. Specifically, a more popular designer can increase the price and product quantity to obtain more profit with less number of product designs, while an un-famous designer can benefit from the high demand variability. Moreover, the numerical analysis shows that the un-famous designer can benefit from increasing product variety, but it is not true for the famous designer.","PeriodicalId":113309,"journal":{"name":"International Journal of Inventory Research","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132371920","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}

The vendor controls the buyer's warehouse, whereas the stock of all finished goods is owned by the vendor. The vendor delivers finished goods to the buyer at a fixed lot size. Shortage is not allowed by controlling the production rate greater than the demand rate. The problem is formulated as a nonlinear cost model which is minimised to arrive at an optimal policy to cooperatively operate the joint contract. An iterative search approach is followed to obtain an optimal value of order quantity and number of shipments. Computational results are presented for a practical example and some empirical studies. The model presented here are applicable in numerous supply chain systems including retail business, assembly and production houses, where two parties are tied together for achieving their common goal.","PeriodicalId":113309,"journal":{"name":"International Journal of Inventory Research","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115202807","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}

Two options for capacity planning are investigated for rapid prototyping with the help of a mixed-integer linear optimisation model: smoothing the capacity utilisation over time vs. a higher level of capacity availability. A sensitivity analysis based on real empirical data in Siemens AG is used for the revealing the impact of workforce and capacity flexibility on operational performance. The results suggest that the number of workers decreases if production orders have not to be completed within only one week. On the contrary, if the binary restriction on the order fulfilment within one week is released, the production orders can be split into different weeks and this results in a higher smoothing rate and thus in a higher capacity utilisation degree.","PeriodicalId":113309,"journal":{"name":"International Journal of Inventory Research","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133070124","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}
