Several criteria affect bidding decisions. Current bidding models determine a markup based on a fixed project construction cost. This work presents a novel bid price determination procedure that is built by integrating a simulation-based cost model and a multi-criteria evaluation model. The cost model is used to consider cost uncertainties and generate a bid price cumulative distribution, where...

one of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. after choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. choosing a mining method depends on the geological and geometrical c...

emergency department has become a useful way to the access to hospital and it is a subject of study for many researchers. the research developed in this paper aims to improve the performance of the emergency department(ed) of sfax hospital. simulation results showed that to manage to increase the number of treated patients and thus to decrease the patient cycle time, it is important to add a sp...

: With the fast development of the E-commerce, it becomes critical to set up an E-commerce Evaluation criteria system. Fuzzy Analytic Hierarchy Process is a new multi-criteria evaluation method evolved from Saaty’s AHP. This paper aimed to find out the key factors that affect success in E-commerce using fuzzy AHP, and give an evaluation method for E-commerce in order to help researches and mana...

This paper deals with evaluation of image segmentation methods. We start with a state-of-the art of the evaluation criteria, involving a reference segmentation or not. Based on an analysis of the main existing criteria, we propose new criteria, when no ground-truth is available. These criteria, based on an energetic formalism, take into account both the complexity of the segmented image, throug...

ecotourism is based on environmental potential and presents an opportunity for suitable utilization and conservation of the sites under management practices, considering accurate planning, potential of the area and people preferences. the present study is conducted to evaluate the ecotourism potential in miankaleh wildlife refuge. the area is located south of the caspian sea. after defining the...

Data mining (DM) techniques are being increasingly used in many modern organizations to retrieve valuable knowledge structures from organizational databases, including data warehouses. An important knowledge structure that can result from data mining activities is the decision tree (DT) that is used for the classi3cation of future events. The induction of the decision tree is done using a super...

A multi-criteria approach is presented for the assessment of alternative means for covering the energy needs (electricity and heat) of an industrial unit, taking into consideration sustainability aspects. The procedure is first described in general terms: proper indicators are defined; next they are grouped in order to form sub-indices, which are then used to determine the composite sustainabil...

In order to address contemporary issues economics and decision sciences need to expand their empirical relevance by introducing more and more realistic (thus more complex) assumptions in their models. One of the most interesting research directions in the field of public economics is the attempt to introduce political constraints, interest groups and collusion effects explicitly (Laffont, 2000)...

This paper deals with the simulation Benchmark multi-criteria evaluation of the performance of control strategies for biological wastewater treatment plants. In particular, the usefulness of more compact multi-criteria measures is discussed. For an illustrative selection of control strategies, an economic index weighing operating costs appears more powerful than a grey-scale presentation approa...
