In this paper, we formulate an optimal control problem to find promotional effort policies for the case when the firm promotes its product at mass and segment specific level in a segmented market. The adoption is measured through the innovation diffusion model with respect to mass and differentiated promotion. The objective of proposed model is profit maximization where the sales evolve through promotion which in turns built up goodwill described by Nerlove-Arrow Model. The solution of the proposed problem is obtained using maximum principle. Some special cases of the proposed optimal control problem are also discussed. The application of the discretized version of the proposed problem is illustrated through a numerical.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122252438","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 environmental and economic aspects, the government has conducted a policy to subsidize the individuals on installing the solar photovoltaic system from both financial assistance and buy-back assurance such as Feed-in Tariff scheme. It is an incentive for people invest such that both economic-benefits of making profits and environment-benefits of reducing carbon emissions can be achieved. Due to the possible risk embedded in this long-term investment, the purpose of this research is to help the investors to evaluate and analyze the expected return and potential risk through a proposed analytical model which determines the optimal installed capacity under the given guaranteed price for specific time period. The model has been applied to an enterprise in Taiwan with sensitivity analysis. The results have shown that the model is able to support decision in maximizing net benefit under uncertainty through the evaluation of the investment with the expected net present value, payback period and internal rate of return.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115884277","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}

Parallel to these developments providers must implement supply chain based data standards to their operations in order to realize system interoperability and comprehensive data integration. Supply chain data standards are universal, unique and unambiguous identifiers for products and locations. Integrating supply chain standards in provider processes, clinical workflow, and ultimately in EHRs offers an ability to track products, serves as a basis for cost and clinical effectiveness, improves patient safety and quality outcomes. In this paper, we present the significance and benefits of adopting and transacting using supply chain data standards, improvement areas within provider operations, potential advantages of integrating supply chain standards with EHRs and barriers to healthcare provider implementation.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131894929","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}

LOPA has found much broader application as a relatively simple risk assessment methodology. However, an important issue faced by risk analysts is how to deal with uncertainties that arise in the elements of the accident scenario like the severity of consequences, frequency data for initiating event, probability of failure of independent protection layers (IPL) and human reliability. (ICAT'14). This paper presents an approach of fuzzy LOPA which takes into account uncertain and/or vague data. A possibilistic representation of data by fuzzy intervals is proposed. Consequence reduced frequency is computed by extended multiplication using a-cuts method. The proposed approach is illustrated by an application to the protection of an operational system which is a heater.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130745960","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}

While a majority of the multi criteria scheduling problems are known to be NP-Hard; near-optimal solution methods exist for quite a number of single criterion and bicriteria scheduling problems. This has encouraged researchers to explore the possibilities of reducing multi criteria scheduling problems to equivalent bicriteria problems. In this work, we demonstrate through experimentation that multi criteria scheduling problems can indeed be reduced to bicriteria scheduling problems. In order to demonstrate this, the multi criteria scheduling problem of simultaneously minimizing the total completion time, total flow time, total lateness, and number of tardy jobs on a single machine with job release dates was explored. Three existing solution methods were tested on 950 randomly generated problems ranging from 3 to 100 jobs. Experimental results show that the multicriteria problem can be reduced to bicriteria problem and solved to obtain near optimal solution by the existing solution method of the reduced problem. However, the concept is valid if there exists a relationship between the original and its equivalent bicriteria problem.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132692704","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}

Due to need to survey movements on the network, estimating ODM is usually considered as a high-cost measure in transportation planning. In this research work, a two-stage procedure, including solving routing problem and minimizing the difference between observed and estimated traffic volumes on the network, has been developed to estimate the O-D matrix elements. At the first stage, routing problem is solved to determine paths while in the second stage an absolute error function has been defined to determine the number of trips from each origin to destination pairs. The procedure has been applied in an illustrative example and results show that the proposed procedure can be utilized for estimating OD matrix elements with a good accuracy.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124506294","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}
