The bid mark-up estimation is an unstructured decision problem that is usually solved by intuition. The aim of this paper is to present a decision support tool so that bid mark-up values may be estimated in a more systematic way. For this purpose, various factors that may affect the level of risk, opportunity and competition in a project option have been identified. Using the 95 cases obtained from the Turkish contractors working in international markets, a case-based reasoning model (CBR) has been developed to estimate the risk, opportunity and competition ratings. These ratings are further converted to risk and profit mark-up values by using linear utility functions constructed according to the boundary values which were identified by the respondents considering worst, average and best scenarios. The applicability of the model has been demonstrated on a real case study.

A SUPPORT VECTOR MACHINE METHOD FOR BID/NO BID DECISION MAKING Sönmez, Rifat (2017-01-01) The bid/no bid decision is an important and complex process, and is impacted by numerous variables that are related to the contractor, project, client, competitors, tender and market conditions. Despite the complexity of bid decision making process, in the construction industry the majority of bid/no bid decisions is made informally based on experience, judgment, and perception. In this paper, a procedure based on support vector machines and backward elimination regression is presented for improving the exi...
Integrated demand and procurement portfolio management with spot market volatility and option contracts Merzifonluoglu, Yasemin (2017-04-01) The newsvendor problem aims to optimally choose a level of order quantity to respond to a known demand distribution with the objective of maximizing expected return. In practice, the decision maker is often challenged with more complex settings involving multiple decisions and uncertainties. For instance, firms may benefit from choosing the set of customer orders to satisfy. It may also be worthwhile for many firms to select a supply portfolio instead of relying on a single procurement mode. This paper prov...
Efficient basket Monte Carlo option pricing via a simple analytical approximation Korn, Ralf; Zeytun, Serkan (2013-05-01) We present a new valuation method for basket options that is based on a limiting approximation of the arithmetic mean by the geometric mean. Using this approximation combined with a new analytical pricing formula for an approximating geometric mean-based option as a control variate, excellent performance for Monte Carlo pricing in a control variate setting is obtained.
A NEW HEURISTIC APPROACH FOR THE MULTIITEM DYNAMIC LOT-SIZING PROBLEM KIRCA, O; KOKTEN, M (Elsevier BV, 1994-06-09) In this paper a framework for a new heuristic approach for solving the single level multi-item capacitated dynamic lot sizing problem is presented. The approach uses an iterative item-by-item strategy for generating solutions to the problem. In each iteration a set of items are scheduled over the planning horizon and the procedure terminates when all items are scheduled. An algorithm that implements this approach is developed in which in each iteration a single item is selected and scheduled over the planni...
The Impact of Modeling on Robust Inventory Management Under Demand Uncertainty Solyali, Oguz; Cordeau, Jean-Francois; Laporte, Gilbert (2016-04-01) This study considers a basic inventory management problem with nonzero fixed order costs under interval demand uncertainty. The existing robust formulations obtained by applying well-known robust optimization methodologies become computationally intractable for large problem instances due to the presence of binary variables. This study resolves this intractability issue by proposing a new robust formulation that is shown to be solvable in polynomial time when the initial inventory is zero or negative. Becau...
