In this thesis, we have proposed a FMCDM model, using Fuzzy DEMATEL, ANP and VIKOR methods for probing the maturity of project team models problems and how to evaluate and create a best implementation for achieving the aspired levels.
In chapter 1, research background and organization of thesis was included. In chapter 2, we introduced the fuzzy set theory. The most critical contribution of fuzzy set theory is its capability of representing imprecise or vague data. Although fuzzy sets have found a great success in engineering, their impact in social sciences has been rather limited. Several scholars have attempted to introduce fuzzy sets concepts to social science community. Preliminaries on fuzzy sets and fuzzy number, 𝛂-cut, and fuzzy linguistic scale are introduced in this chapter.
In chapter 3, we have discussed the definitions and theory of fuzzy multiple criteria decision making method. A hybrid MCDM model combined with Fuzzy DEMATEL and ANP for evaluating and improving problems is more suitable in the real world than the previously available methods under complex environments and situations in dynamics, dependence and feedback among dimensions and criteria. The VIKOR method was developed for multicriteria optimization of complex systems. It determines the compromise ranking-list, the compromise solution, and the weight stability intervals for preference stability of the compromise solution obtained with the initial (given) weights. This method focuses on ranking and selecting from a set of alternatives in the presence of conflicting criteria. It introduces the multicriteria ranking index based on the particular measure of ―closeness‖ to the ―ideal‖ solution.
In chapter 4, we have proposed the concept of project maturity and model.
Maturity is the quality or state of being mature. If we apply the concept of maturity to an organization it might refer to a state where the organization is in a perfect condition to achieve its objectives. Project maturity would then mean that the organization is perfectly conditioned to deal with its projects. First, we have considered capability maturity model for software, K-PMMM and OPM3. Then, we found the dimension and criteria of HPPT, PTEM and AIPT model based on expert judgment and literature.
In chapter 5, we adopt Fuzzy DEMATEL to build up a structure model of teamwork competency evaluation system of HPPT, PTEM and AIPT. And then combining ANP, convert the attribution impact of teamwork competency evaluation criteria in the importance degree of each project maturity team, and establish teamwork competency assessment model. Finally, apply VIKOR to evaluate the teamwork performance of HPPT, PTEM and AIPT, and find out the case (A
corporation) which was identified to have the worst attribute according to teamwork competency of team. In the end, a decision was made through system structure model and concrete improvement strategies are proposed.
The following summarizes the important findings of this thesis. Using the Fuzzy DEMATEL in conjunction with an ANP, we can discover the relative weights of various criteria. The Fuzzy DEMATEL works in an ANP to construct a building decision model and influence degree for high performance project team (HPPT), project team effectiveness maturity (PTEM) and agile Innovation project team (AIPT), which may be worthy subjects of further research. The Fuzzy DEMATEL technique carries out the comparisons in pairs of mutual relationships. This surveys the materials and clarifies the essence of problems based on the novel hybrid MCDM model method, and it may help to make future plans. In addition, the model is well suited to deal with decision problems, whose constructs are complicated and whose criteria are interdependent. Because the factors possessed interrelations and self-feedback relationships proved by the Fuzzy DEMATEL technique, then ANP was utilized to calculate each weight of the criteria. Furthermore, uses VIKOR method to analyze the performance of HPPT, PTEM and AIPT to indicate the criteria‘s gap to anticipated level for managers to improve the team maturity of project.
In the future, we advise to keep in researching about the dimension of external environment which is including some criteria like human, finance, resources, and organization supports. Then, to recognize the relative superiority and degree of maturity in the cross-sectional domestic enterprises after they adopt project team management method for providing a reference to domestic enterprises targets about team promoting and team management methods.
