A mathematical model of (ILPb), which is an MPEC problem, is constructed based on duality theories, and then a necessary and sufficient condition of checking the feasibility of (ILPb) is provided. The inverse problem under $l_1$ norm is transformed into a problem under weighted sum-type Hamming distance with linear equality and inequality constraints. An optimal solution in the special case is also given when the dual constraint conditions are all equalities and the coefficient matrix is invertible. In this case, the system of linear equations has the only solution.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129173847","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 simulation model is divided into three sub-models: the core model defines the basic structure of the simulation scenario, the data model maintains the detailed information of the simulation model, and the runtime model manages work flows and object life-cycles during simulation. Then the three sub-models are linked through a creative \"composite\", which is a special component describing the relationships between the sub-models. Neutral interfaces are provided to make outer tools in using transparent to the simulation system. Empirical results show that the implemented simulation system can model and analyze various supply chains and users can extend the existing simulation components easily. The research in the paper can cope with the increasing demand of supply chain simulation, and thus enable more economic and efficient quantitative analysis on supply chain.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121522326","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}

There are numerous risk factors exist in the investment process, and most of them are varied and changeable, such as the change of market supply and demand, policy adjustment, and the change of interest rate, all these factors impose direct influence on the success of the investment. The risk management standards of real estate enterprises in China are still at relative low level, which lack the risk management to the whole process of the project, and also there exist problem as inadequate market research, excessive depend on bank, ineffective management, and inadequate brand awareness. This paper evaluates the risk with Fuzzy Comprehensive Evaluation method and puts forward the detailed prevention strategies towards these risks through analyzing the risk factors in the whole investment stage of decision-making, preparatory construction, construction, and sale. The real estate enterprises should take the quality management from the beginning to the end of the project, and do a solid feasibility study of project .
