Topsis Model

By analysising the disadvantages of the current bid evaluation methods used in highway project,the article builds up TOPSIS model based on coefficient of entropy to evaluating bidding units. First,the weight of each index is calculated by means of entropy weight coefficient method. Then it makes comprehensive assessment about bid evaluation with entropy weight coefficient method and TOPSIS method. The proposed method is applied to evaluating information system integration solutions and satisfactory results are abtained.

Need For Information

The need for information system integration is typical for many companies including small and medium-sized enterprises (SMEs). But especially for SMEs, the costs to run a full-fledged integration platform in-house are beyond the available IT budget. This article describes the concept of Orchestration as a Service (OaaS), a specialization of the Platform as a Service (PaaS) paradigm in the Cloud (computing) world. The goal of this paradigm is to provide a workflow-based integration platform as a (Cloud) service focusing on so-called service orchestrations. We present the BIS-Grid Engine as a core middleware for an OaaS infrastructure including a discussion about how our solution addresses security requirements that are a key issue in Cloud technologies.
