Due to this advantage the retailer also offers a fixed credit period to all its customers to boost the demand. Demand also depends on stock and selling price. A Genetic Algorithm (GA) with chromosome\u2019s life-time dependent varying population size is used to solve the model where, at the time of generation of initial population, diversity in the population is maintained using information entropy theory. In the algorithm crossover probability of a pair of parents is a function of their age-type (young, middle-aged, old, etc.) and is obtained using a fuzzy rule base and possibility theory. A fuzzy possibility\/necessity based evolution process is proposed to deal with fuzzy objective function.<\/p>","DOI":"10.4018\/jsds.2012040104","type":"journal-article","created":{"date-parts":[[2012,5,16]],"date-time":"2012-05-16T09:57:17Z","timestamp":1337162237000},"page":"47-65","source":"Crossref","is-referenced-by-count":12,"title":["Inventory Policy with Stock, Price and Credit-Linked Demand"],"prefix":"10.4018","volume":"3","author":[{"given":"Partha","family":"Guchhait","sequence":"first","affiliation":[{"name":"Vidyasagar University, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pravash Kumar","family":"Giri","sequence":"additional","affiliation":[{"name":"Vidyasagar University, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manas Kumar","family":"Maiti","sequence":"additional","affiliation":[{"name":"Mahishadal Raj College, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manoranjan","family":"Maiti","sequence":"additional","affiliation":[{"name":"Vidyasagar University, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"jsds.2012040104-0","doi-asserted-by":"crossref","first-page":"658","DOI":"10.1057\/jors.1995.90","article-title":"Ordering policies of deteriorating item under permissible delay in payments.","volume":"46","author":"S.
