It requires vendors to have a complete knowledge of their purchaser's demands. In such a situation, the vendor shall manage the supply with comparatively more inventory at its end. The operational cost can further decrease provided supply is in sub-batches and logistics cost does not increase substantially. However, determining the right size for these sub-batches becomes an issue. Sub-batches of varying size may cause planning and control problems, but supply in sub-batches of uniform size will not. <\/jats:p><jats:p> In this paper, joint economic lot size models are presented for the two supply situations, namely staggered supply and uniform supply. Cases are employed that describe the inventory situation of a single vendor supplying an item to a manufacturer that is further processed before it is supplied to the end-user. Using illustrative examples, the comparative advantages of the uniform sub-batch supply over the staggered alternative are investigated. From the analysis, uniform supply models are found to be comparatively more beneficial and robust than the staggered sub-batch supply. <\/jats:p>","DOI":"10.1142\/s0217595911003259","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T22:31:16Z","timestamp":1308349876000},"page":"301-322","source":"Crossref","is-referenced-by-count":2,"title":["A VENDOR MANAGED TWO-ECHELON INVENTORY SYSTEM FOR AN INTEGRATED PRODUCTION PROCUREMENT CASE"],"prefix":"10.1142","volume":"28","author":[{"given":"ABHIJEET","family":"SINGH","sequence":"first","affiliation":[{"name":"Faculty of Management Studies, BHU, Varanasi 221005, India"}]},{"given":"SAROJ","family":"KOUL","sequence":"additional","affiliation":[{"name":"Jindal Global Business School NCR, 131001, India"}]},{"given":"ANIL K.","family":"AGRAWAL","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering BHU, Varanasi 221005, India"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1057\/jors.1995.52"},{"key":"rf3","first-page":"292","volume":"16","author":"Banerjee A.","journal-title":"Decision Sciences"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1108\/01443579510099760"},{"key":"rf5","first-page":"119","volume":"28","author":"Chatterjee A.
