The MADM methods incorporate mechanisms of building preference models based on information obtained from the DM. In a wide variety of such methods, the DM is supposed to provide information in terms of weights of criteria, usually understood as criteria’s priorities. These weights serve as parameters of the method- specific preference models. The DM can define weights directly, or by using special weight elicitation techniques such as AHP, MAVT and others. Our concerns are that when using weight-based methods, the DM cannot ensure the correctness of the preference model. First, different weight-based methods use different kinds of preference models, which prioritize criteria based on weights in different manners. Second, interpretation of weights in some MADM methods is far from intuitive. Thus, a situation may occur when an inexperienced DM thinks of weights differently than they actually work in the method, and expresses the preference information incorrectly. In this paper we demonstrate the differences between how weights are interpreted in several methods: simple additive weighting, TOPSIS, VIKOR and PROMETHEE. We do it by comparing rankings produced with methods based on randomly generated data. We demonstrate that differences of interpreting weights significantly contribute to differences in produced rankings. A solution to this problem could be twofold: first, increasing awareness of differences between method-specific weight-based prioritizing mechanisms, and second, providing interpretations of weights for popular methods in the language understandable by the DMs.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"37 1","pages":"191-202"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88367977","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}

A bus service model had been constructed with a rectangular service zone where costs are synthesized by an exponential relation.

This paper examines another model with capacity constraint to show that previous formulated optimal solution contains questionable findings and then we provide our solution approach. The key feature of our paper is to point out that using the route width as a continuous variable will derive unreasonable results. Our improved approach is to use the partition number for the zone width as a discrete variable. A numerical example is provided to illustrate our proposed approach.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"11 1","pages":"61-72"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82974451","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}

Thereafter, most smartphone manufacturers begin to mimic this innovation in their new generation products for a dramatically increasing demand market. Although the smartphone market includes many types and functions of products, there are no smart- phone selection methods to support customers to select an effective smartphone. In order to cope with such a problem, this paper proposes a multi-criteria selection method to evaluate operating systems and hardware and software specifications using AHP and SMART-ROC, respectively. For illustration, this paper uses the proposed methods to analyze the customer utility and benefit-cost of 24 popular smartphones in the market. The results show that the most popular smartphone does not have the best cost-benefit. This paper suggests customers select smartphones by referring to the cost-benefit approach except when they are looking for a communications product for a special purpose.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"48 1","pages":"41-60"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90731303","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 a batch manufacturing process, products are produced batch-by-batch. Thus, total process variations are generally divided into batch-by-batch variation and within-batch variation. The main purpose of this study is to provide an efficient method for testing the batch-processing process yield. Base on the one-way random effect model, the generalized pivotal quantity is utilized to establish the generalized confidence interval for assessing the process yield index. By simulations, the proposed method shows that its empirical coverage probability is not affected by the batch effect, and is still close the nominal coverage probability as the batch size increases.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"35 1","pages":"1-16"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87153599","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, knowledge searching is a very time-consuming work. Additionally, in the context of an unsolved puzzle or unknown task, users typically have to determine the knowledge for which they will search. Therefore, knowledge management platforms for enterprises should have knowledge recommendation functionality. Hybrid recommendation systems (RS) have been developed to overcome, or at least to mitigate, the limitations of collaborative filtering. Because Genetic Algorithm (GA) is good at searching, it can cluster data according to similarities. However, the increase in the amount of data and information reduces the performance of a GA, thereby increasing cost of finding a solution. This work applies a novel method for incorporating a GA and rough set theory into clustering. In this paper, this work presents a hybrid knowledge recommendation model, which has a two-phase model for clustering and recommending. Approach implementation is demonstrated, as are its effectiveness and efficiency.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"91 1","pages":"17-39"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73703509","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 order to expand their market share and attract new users, new generations of smartphones are being introduced in a much shorter interval. As a result, older phones are discarded in greater speed, and thus creating more electronic waste each year. To reduce waste material, the concept of reused smartphones is proposed. In order to attract users to purchase these reused smartphones, this study aims to look into the pricing strategy for Apple and Samsung products as both are top smartphone brands with the highest market shares. Under the duopoly environment, this study uses the Cournot game model to determine the optimal solution in a price competition with Apple set to be the leader and Samsung the “follower”. While making pricing strategies, manufacturers commonly strive to maximize their profits. Two pricing functions will have a point of intersection, and the solution will be the optimal equilibrium. The model proposed in this study may be taken as reference for manufacturers to understand the reused smartphone market.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"79 1","pages":"405-422"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90617580","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}

If the failed unit is not detected, the system enters an unsafe failure state and has to be refreshed by a reboot action. When the service station breaks down, it needs repair at a repair device. We present the expression for reliability function R Y ( t ) and mean time to system failure MTTF . Several cases are analyzed to study the effects of various parameters on the system reliability R Y ( t ) and MTTF . We also perform the sensitivity analysis of R Y ( t ) and MTTF with respect to system parameters.
