This study aims to make field return rate predictions for a particular scenario, the one where multiple products have a similar design and discrete-type laboratory data together with continuous-type field data is available for each product. We build a hierarchical model to link the laboratory and field data on failure. The efficient sharing of information among products means that the proposed method generally provides a more stable laboratory summary for each individual product, especially for those cases with few or even no failures during the laboratory testing stage. Furthermore, a real case study is used to verify the proposed method. It is shown that the proposed method provides a better connection between laboratory reliability and field reliability, and this leads to a significant improvement in the estimated field return rate.","PeriodicalId":13379,"journal":{"name":"IIE Transactions","volume":"48 1","pages":"710 - 719"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0740817X.2015.1133941","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59754428","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 particular, the uncapacitated two-level serial lot sizing problem with backlogging and the two-level serial lot sizing problem with cargo capacity and backlogging are formulated using effective shortest-path network representations, which define the convex hull of their feasible solutions. These representations lead to efficient algorithms with O(T3) time for the uncapacitated problem and O(T6) time for the capacitated problem. Furthermore, a tight reformulation with O(T3) variables and O(T2) constraints (resp.

Existing vehicle routing navigation systems, whether built-in or portable, lack the ability to rely on online servers. Such systems must compute the route in a stand-alone mode with limited hardware processing/memory capacity given an origin/destination pair and departure time. In this article, we propose a computationally efficient, yet effective, hierarchical algorithm to solve the time-dependent shortest path problem. Our proposed algorithm exploits community-based hierarchical representations of road networks, and it recursively reduces the search space in each level of the hierarchy by using our proposed search strategy algorithm. Our proposed algorithm is efficient in terms of finding shortest paths in milliseconds for large-scale road networks while eliminating the need to store preprocessed shortest paths, shortcuts, lower bounds, etc. We demonstrate the performance of the proposed algorithm using data from Detroit, New York, and San Francisco road networks.","PeriodicalId":13379,"journal":{"name":"IIE Transactions","volume":"48 1","pages":"158 - 169"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0740817X.2015.1078523","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59752224","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}

It is assumed that components in the system degrade continuously through an additive impact under load. The reliability assessment of such systems is often complicated by the fact that both the arriving load and the failure of components influence the degradation of the surviving components in a complex manner. The proposed approaches seek to ease this problem, by first deriving the time to prior failures and the arrival of random loads and then determining the number of failed components. Two separate models capable of analyzing system reliability as well as arriving at system maintenance and design decisions are proposed. The first considers a constant load and the other a cumulative load. A numerical example is presented to illustrate the effectiveness of the proposed models.","PeriodicalId":13379,"journal":{"name":"IIE Transactions","volume":"48 1","pages":"699 - 709"},"PeriodicalIF":0.0,"publicationDate":"2016-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0740817X.2015.1125041","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59753913","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}

However, mixed-type data consisting of both continuous and categorical observations are becoming more common in modern manufacturing processes and service management. However, they cannot be analyzed using traditional methods. By assuming that there is a latent continuous variable that determines the attribute levels of a categorical variable, the ordinal information among the attribute levels can be exploited. This enables us to simultaneously describe and monitor continuous and categorical data in a unified framework of standardized ranks, based on which a multivariate exponentially weighted moving average control chart is proposed. This control chart specializes in detecting location shifts in continuous data and in latent continuous distributions of categorical data. Numerical simulations show that our proposed chart can efficiently detect location shifts and is robust to various distributions.","PeriodicalId":13379,"journal":{"name":"IIE Transactions","volume":"48 1","pages":"673 - 683"},"PeriodicalIF":0.0,"publicationDate":"2016-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0740817X.2015.1126002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59754606","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}

We present an original model to estimate such effects and select the optimal preventive maintenance intervals and contract terms for pieces of equipment that are serviced by an external party. In the context of the contract, the intention of each party is in general to maximize its own profit, which usually leads to unaligned interests and decisions. To resolve this issue, we propose incentive schemes to ensure the contract sustainability by achieving channel coordination between the client and its service vendor. Special focus is put on how the performed net-present-value analysis of both parties affects decision-making regarding equipment maintenance. Our model considers a new alternative of negotiating contracts with non-constant maintenance intervals. The proposed model helps to identify conditions that justify maintenance deferrals with their associated negligence, in terms of life cycle reduction and performance deterioration, when no channel coordination is promoted. Additionally, we present a simple procedure to settle an optimal contract duration, benefiting both parties. The proposed methodology is tested using a baseline case study from the literature. It illustrates how return-on-investment analysis may significantly impact optimal maintenance intervals during the contract for both parties. Accordingly, incentives need to be re-evaluated to achieve channel coordination. The suggested approach can be easily implemented in commercial spreadsheets, facilitating sensitivity analyses.","PeriodicalId":13379,"journal":{"name":"IIE Transactions","volume":"52 1","pages":"651 - 660"},"PeriodicalIF":0.0,"publicationDate":"2016-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0740817X.2015.1122255","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59753818","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}

Managing such a heterogeneous, transient, and non-stationary system is a tremendous challenge. We take an unconventional approach, in that we force the queue lengths in each powered-on server to be time-stable (i.e., stationary). It allows the operators to guarantee performance and effectively monitor the system. We formulate a mixed-integer program to minimize energy costs while satisfying time-stability.

Both the conditional case (CUSUM chart without restarting) and the cyclical case (CUSUM chart with restarting) are considered. It is shown that the distribution of CUSUM charts both with and without restarting approaches a stationary distribution, independent of their initial values.
