The incoming heterogeneous calls are categorized as handoff calls and new calls. The arrival and service processes of both types of calls follow marked Markovian arrival process (<inline-formula><tex-math id=\"M4\">begin{document}$ M!M!A!P $end{document}</tex-math></inline-formula>) and <inline-formula><tex-math id=\"M5\">begin{document}$ P!H $end{document}</tex-math></inline-formula> distribution with distinct parameters, respectively. An arriving new call will be blocked when all the channels are occupied, and consequently will join the orbit (virtual space) to retry following <inline-formula><tex-math id=\"M6\">begin{document}$ P!H $end{document}</tex-math></inline-formula> distribution. When all the channels are occupied and a handoff call arrives at the system, out of the following two scenarios, one might take place. In the first scenario, if all the channels are occupied with handoff calls, the arriving handoff call will be lost from the system. While in the second one, if all the channels are occupied and at least one of them is serving a new call, the arriving handoff call will be provided service by using preemptive priority over that new call and the preempted new call will join the orbit. Behaviour of the proposed system is modelled by the level dependent quasi-birth-death <inline-formula><tex-math id=\"M7\">begin{document}$ (L!D!Q!B!D) $end{document}</tex-math></inline-formula> process. The expressions of various performance measures have been derived for the numerical illustration.

The results show that: the fresh-keeping and low-carbon efforts made by fresh produce suppliers are related to consumers' preferences, fresh-keeping costs, low-carbon costs, fresh-keeping carbon emission factors, and carbon reduction efficiency; under certain conditions, both the cost sharing contract and the two-part pricing contract can coordinate the supply chain of fresh agricultural products; given certain costs and carbon reduction efficiency, which contract retailers choose depends on consumers' consumption preferences and the size of the supplier's initial carbon emissions; when both contracts are valid, it is more advantageous for the retailer to choose two-part pricing contract; the higher the carbon trading price, the better the incentive effect on suppliers' fresh-keeping efforts and low-carbon efforts.","PeriodicalId":347719,"journal":{"name":"Journal of Industrial & Management Optimization","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125102624","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}

Considering that the saddle point solution of the differential game usually results in solving a high-dimensional (24 dimensional in this paper) two-point boundary value problem (TPBVP) that is challengeable, a dimension-reduction method is proposed in this paper to simplify the solution of the 24-dimensional TPBVP related to the finite-horizon SPE game and to improve the efficiency of the saddle point solution. In this method, firstly, the 24-dimensional TPBVP can be simplified to a 12-dimensional TPBVP by using the linearization of the spacecraft dynamics; then the adjoint variables associated with the relative state variables between the pursuer and evader can be expressed in the form of state transition; after that, based on the necessary conditions for the saddle point solution and the adjoint variables in the form of state transition, the 12-dimensional TPBVP can be transformed into the solving of 6-dimensional nonlinear equations; finally, a hybrid numerical algorithm is developed to solve the nonlinear equations so as to obtain the saddle point solution. The simulation results show that the proposed method can effectively obtain the saddle point solution and is robust to the interception time, the orbital altitude and the initial relative states between the pursuer and evader.","PeriodicalId":347719,"journal":{"name":"Journal of Industrial & Management Optimization","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127983855","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}

Our goal in this research is to examine how the multi-channel retailer's online channel design interacts with its price self-matching strategy in a supply chain including a multi-channel retailer and an e-retailer. Our study demonstrates that adopting price self-matching does not necessarily benefit the multi-channel retailer. Moreover, price self-matching can greatly impact the performance of the multi-channel retailer's online channel design, for example, under some market conditions where the multi-channel retailer can benefit from price self-matching only if it employs the e-retailer's e-marketplace, the multi-channel retailer should design online channel according to the e-marketplace's commission rate; but under other market conditions, it should always establish self-operated online channel. Overall, only the strategy of establishing self-operated online channel and adopting price self-matching and the strategy of employing the e-retailer's e-marketplace and adopting price self-matching can help the two retailers achieve a win-win situation. Furthermore, we show that, interestingly, a more prominent disadvantage of the self-operated online channel's potential demand benefits not only the e-retailer but also the multi-channel retailer.","PeriodicalId":347719,"journal":{"name":"Journal of Industrial & Management Optimization","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134593041","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}

Organizations and companies face various uncertainties, and this makes it extremely difficult and complex to evaluate their efficiency. In this research, opened-network data envelopment analysis models have been developed in uncertain space for three uncertain states, including: uncertain outputs, uncertain inputs, and simultaneous uncertain inputs and outputs. The proposed models have been used to evaluate the efficiency of 10 two-stage processes, seller and buyer in a supply chain, and the impact of data uncertainty is examined. The results obtained from the developed models have been compared with the results of traditional DEA network models. The validity and accuracy of the developed models have also been examined. The results have shown that the reliability of the proposed models is higher than the traditional DEA network model. Also, by examining the efficiency of decision-making units in different conditions of data uncertainty and deviations, it was determined that the greater the range of this deviation, the lower the efficiency score of different units will be, which is consistent with reality.","PeriodicalId":347719,"journal":{"name":"Journal of Industrial & Management Optimization","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117085771","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}
