In the modern advertising agency selection contest, each participating agency specifies not only its proposed creative campaign but also the budget required to purchase the agreed-on media. The advertiser selects the agency that offers the best combination of creative quality and media cost, similar to conducting a score auction. To participate in the contest, each agency needs to incur an up-front bid-preparation cost to cover the development of a customized creative campaign. Agency industry literature has called for the advertiser to fully reimburse such costs to all agencies that enter the contest. The authors analyze the optimal stipend policy of an advertiser facing agencies with asymmetric bid-preparation costs, such that the incumbent agency faces a lower bid-preparation cost than a competitor agency entering the contest. The authors show that reimbursing bid-preparation costs in full is never optimal, nor is reimbursing any part of the incumbent's bid-preparation cost. However, a stipend that is strictly lower than the competitor's bid-preparation cost can benefit the advertiser under certain conditions. The authors provide a sufficient condition (in terms of the distribution of agency values to the advertiser) for such a new-business stipend to benefit the advertiser.

Abstract The problem under consideration is the cost estimation and consequent bid preparation for machined parts subcontracted to mechanical small and medium enterprises (SME). This activity, i.e. cost estimation and corresponding bid preparation, becomes more and more important due to the increasing and globalized competition in this market. There is, therefore, a clear need for precise and accurate cost estimation of machined parts in order for a small company to justify its prices. The proposed prototype software system is based (i) on a manufacturing feature based product description of the part to be machined and (ii) on a non-linear model of its process plan using Petri nets, taking into consideration processing alternatives and precedence constraints, which allows a heuristic based best search of the process plan and, consequently, the corresponding machining time and cost. Product description is done interactively through user friendly interfaces and the corresponding process planning model is constructed automatically in the form of a Petri net. Machine tools and their characteristics are selected from a customized database. Tools and machining parameters are selected through a link with the tool management software TOOL Light©. Minimum time or cost process plans and corresponding bids are reported using the Petri net model of the machined part under consideration and using machining heuristics. The type of parts that are considered in our application are rotational or prismatic parts that are used as components in complex machines like machine tools or automatic assembly machines.

This paper presents a computer system developed to assist earthmoving contractors in preparing proposals. It can also be used by owners and (or) their agents to plan and estimate the cost and duration of earthmoving projects. This is particularly useful for large projects where owners need to define a feasible scope of work that suits their budgets and operating plans. The system has been developed utilizing computer simulation. This paper provides an overview of the developed system and briefly describes its basic components, focusing primarily on the development of the system's database and the procedure used to account for indirect cost components of this class of projects. The paper also demonstrates the capabilities of the developed system in selecting most-suitable equipment fleets, from available equipment, that meet the terms and conditions outlined in bid documents. A project example is analyzed to demonstrate the essential features of the developed system.Key words: bid preparation, earthmoving, equipment database, indirect cost, computer simulation.

Over the past ten years, the Maritime Administration (MARAD) has awarded and administered contracts for the major conversion of 15 vessels. Each of these projects involved vessel reactivation as well as conversion, and each contract was awarded on a fixed price basis. The combination of fixed pricing and vessel conversion/reactivation creates a challenge to shipyards bidding for the contract in that price competition is intense while, at the same time, an unknown level of growth work can be expected in the vessel reactivation portion of the project. Moreover, the project being bid, inclusive of anticipated growth work, must be integrated into the overall orderbook within the shipyard. The need for careful planning by the shipyard from the beginning of bid preparation through the end of the performance period is clearly evident. This SNAME paper, however, addresses not shipyard planning but continuing project monitoring and progress evaluation by the shipyard's customer. Such monitoring includes ongoing comparisons between the shipyard's planned and actual performance with respect to resource application and schedule adherence. From a technical standpoint, it involves compliance with contract and specification requirements. And finally, from a financial standpoint, it includes project progressing to provide the basis for periodic payments to the shipyard for completed work.
