PSO algorithm has shown some important advantage by providing high speed of convergence in specific problems, but it has a tendency to be trapped in a near optimal solution and difficult in improving the accuracy by fine tuning. This paper proposes a dynamic local and global conjoint particle swarm optimization (DLGCPSO and DCPSO in short) algorithm of which all particles dynamically share the best information of the local, global and the group particles. It is tested with a set of eight benchmark functions with different parameters in comparison to PSO. Experimental results indicate that the DCPSO algorithm improves the search performance on the benchmark functions significantly, and shows the effectiveness in solving optimization problems.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"25 1","pages":"1-16"},"PeriodicalIF":0.0,"publicationDate":"2014-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82595147","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 examine the effect of the knowledge management infrastructure, knowledge management capability and job satisfaction on organizational loyalty, this study conducted Structural Equation Modeling (SEM) to test the hypotheses with 399 questionnaires of hospital administrative staffs in Taiwan. In exploration of the model of this study, it was found that the factors greatly influencing organizational loyalty of hospital administrative staffs, in turn, were knowledge management infrastructure, job satisfaction, and knowledge management capability. The results of this research can help the authorities of hospitals to understand their staffs' job satisfaction and organizational loyalty, which will allow authorities to take the steps necessary to increase job satisfaction and organizational loyalty. Research implications and directions are discussed.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"1 1","pages":"17-33"},"PeriodicalIF":0.0,"publicationDate":"2014-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84719195","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 selling probability of recycling products is sensitive to their price and availability. This assumption is rational because price and availability often influence customer demand. The study also assumes that the three quality levels of collected returns exist, which affect the price they are sold for. This paper determines optimal selling prices for re-manufacturers. The exact closed-form solution is then derived and total profit is maximized to create the remanufacturing model. A numerical example and sensitivity analysis are conducted to demonstrate the model. The study provides managerial insights on the benefits of revenue management for product reuse. For example, if manager can develop an incentive return-subsidy policy to encourage consumer to offer better or more returns, the profits will increase more.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"75 1","pages":"51-66"},"PeriodicalIF":0.0,"publicationDate":"2014-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74067707","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}

This paper presents an integrated inventory quality improvement investment and crashing cost by simultaneously optimizing the optimal order quantity, lead time, process quality and number of deliveries for non defective and defective items. Negative exponential lead time crashing cost is considered in the proposed model. Lead time is an important element in any inventory management system. In many practical situations, lead time can be reduced by an additional crashing cost, that is, lead time is controllable. Here, the buyer lead time can be shortened by paying an additional crashing cost which is negative exponential function of lead time. The objective is to minimize the total cost incurred by the vendor and the buyer. In this study first, we developed mathematical model and procedure of finding the optimal solution is developed. An iterative procedure is developed to find the optimal solution and numerical examples are presented to illustrate the result of the proposed model. The result are illustrate with the help of numerical example. Graphical representation is also presented to illustrate the proposed model.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"33 1","pages":"307-327"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81321382","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, when the service area is large and job density is low, couriers frequently travel a long distance to serve a few customers. Service inefficiency can be attributed to inherent lacking of economies of scale and reflects on tough tradeoffs between courier utilization and customer waiting time. In this paper, operational policy design of courier services is addressed aiming at reducing both workload and waiting time. Regression metamodels of tour length are first constructed by simulation. Mean-value performance analysis of a new policy of hub transshipment across flexible time periods contrast to the periodical routing policy is next presented. Applicability condition of the new policy is provided. Finally, dynamic operation of the policy is illustrated with styled data of courier service at a large hospital.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"49 1","pages":"363-380"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74574992","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 shift between attack and defense is involved with a short span of time difficult to define in concrete format. This paper extends Chen and Chu's model of the Ardennes campaign of World War II using the Lanchester equations. We use a new variable, deadlocked situation, to represent the shifting time between attack and defense. This article divides the Ardennes Campaign into three periods: (a) the initial period, German attacked while the Allies defended; (b) the middle period, both sides seized the initiative; (c) the final period, Allies attacked while Germans defended. In this paper, we apply Lanchester's Square Law to estimate the casualties by determining the shifting time between attack and defense. We obtain improved goodness of fit for the historical data.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"72 1","pages":"349-362"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82042953","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}

From 2012 brand value report of BrandZ, Google is selected as the word mark sample in this study, tending to understand the confusion of graphic designers and consumers in the four similar patterns. Aiming at 34 graphic designers with more than 2-year design experiences and 30 consumers, the similarity test of trademark samples is proceeded to construct the trademark map presented by the graphic designers and consumers for detailed analyses and cognitive differences. The experimental results show judging differences in trademark similarity between the two groups that Font Similar is the major factor in trademark confusion. However, graphic designers are not likely to confuse Pronunciation Similar, and consumers do not easily confuse Alphabet Similar. The results could guide enterprises to the concept of trademark map when designing trademarks so as to obtain the optimal brand orientation.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"3 1","pages":"265-277"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88863878","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}

Hence, here, a budget constraint on total inventory investment and a maximum permissible storage space constraint are added simultaneously to a stochastic continuous review inventory system. The piece-wise linear crashing cost function which is widely used in project management is considered in this paper. The study relaxes the assumption about the form of distribution function of lead time demand by only assuming the mean and standard deviation of lead time demand are known. A minimax distribution free procedure is developed for the constrained problem. This study also shows that the respective budget and storage space constrained inventory model to be minimized is jointly convex in the decision variables. A numerical example is given to illustrate the discussed model.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"28 1","pages":"175-192"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83377162","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}
