That is, the facility provides a benefit or service to society, while adversely affecting the quality of life or social values in a number of possible ways. The paper proposes a location model for a new semi-desirable facility that accounts for the service costs by a standard minisum objective with arbitrary travel distance function. The social costs are imputed by specifying around each demand point or population center a convex forbidden region, also defined by an arbitrary distance metric, in which the new facility may not be located. A general solution algorithm is suggested, and the methodology is applied to circular forbidden regions and special travel distance functions.</p></div>","PeriodicalId":100880,"journal":{"name":"Location Science","volume":"6 1","pages":"Pages 109-120"},"PeriodicalIF":0.0,"publicationDate":"1998-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0966-8349(98)00050-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72110414","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}

Therefore, in some branches of optimization, such as scheduling and queuing theory, classification is a widely used tool.</p><p>The aim of this paper is to propose a 5-position classification that can be used to describe all location models. We provide a list of currently available symbols and indicate their usefulness in a (necessarily non-comprehensive) list of “classical” location models.

In this paper, a covering-type model for two-tiered EMS systems is considered.

In the public sector, agencies such as the US Forest Service manage millions of acres of land. In the private sector, large forest product companies also own and manage millions of acres. Many countries, like Ireland and Finland, utilize large-scale models to optimize the present value of forest activities and outputs. Forest planning can be viewed as a multi-level management problem. The highest or strategic level involves identifying feasible outputs and goals for long-term operations over decades. The middle or tactical level of analysis is associated with determining specific levels of activities on large tracts of land. At the lowest or operational level, specific stands of timber are slated for harvesting, roads are scheduled to be built or improved, and harvesting systems are designed to minimize the cost of extracting trees across the terrain. Each level of analysis often involves numerous locational decisions. Our objective is to provide a review of forest modeling that highlights many of the locational issues found in forest management.</p></div>","PeriodicalId":100880,"journal":{"name":"Location Science","volume":"6 1","pages":"Pages 137-153"},"PeriodicalIF":0.0,"publicationDate":"1998-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0966-8349(98)00051-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72116185","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}
