Block sourcing plus

چکیده
• We analyse procurement from suppliers with diseconomies of scale in production. Buyer can increase his surplus holding a split-award auction before setting price. Optimally leaves one supplier without lot and size is inefficiently large. All are active make positive profit. study how buyer unable to (directly) price discriminate should satisfy demand for divisible good, produced increasing marginal cost. As expected, we find that dynamic pricing cannot, while auctioning contracts lots ( block sourcing ) need not, lead higher than (classical monopsony). However, show the optimal combination residual supply always strictly superior. Thus, provide rationale two-stage contracting even absence uncertainty.

Kronecker product approximations for dense block Toeplitz-plus-Hankel matrices
In this paper, we consider the approximation of dense block Toeplitz-plus-Hankel matrices by sums of Kronecker products. We present an algorithm for efficiently computing the matrix approximation that requires the factorization of matrices of much smaller dimension than that of the original. The main results are described for block Toeplitz matrices with Toeplitz-plus-Hankel blocks (BTTHB), but...
متن کاملParavertebral Block Plus Thoracic Wall Block versus Paravertebral Block Alone for Analgesia of Modified Radical Mastectomy: A Retrospective Cohort Study
BACKGROUND AND OBJECTIVES Paravertebral block placement was the main anesthetic technique for modified radical mastectomy in our hospital until February 2014, when its combination with blocks targeting the pectoral musculature was initiated. We compared the analgesic effects of paravertebral blocks with or without blocks targeting the pectoral musculature for modified radical mastectomy. METH...
متن کاملSingle sourcing versus dual sourcing under conditions of learning
This paper considers a buyer who has to decide whether to select a single or two sources of supply for a homogeneous product. The production processes of the suppliers are subject to learning effects, which reduce the production costs and increase the production capacities of the suppliers. This, in turn, enables the suppliers to reduce the sales price, which results in lower acquisition costs ...
متن کاملThe Mexico-China Sourcing Game: Teaching Global Dual Sourcing
W describe a three-hour class on global dual sourcing built around a game that demonstrates the challenges in making operational decisions, and transfers recent academic insights to the classroom. Student teams manage a firm with access to a responsive but expensive supply source (Mexico) and a cheap but remote source (China). Each team must determine a sourcing strategy to satisfy random deman...
