    Application of multi criteria decision making to simulate uncertainties in construction projects
    (AIKTC, 2018) Magar, Rajendra; Katrekar, Shweta (16CEM06)
    Uncertainty certainly affects the performance of a construction project. It can be generalized as the difference between result and outcomes from usually expected values. The values can be considered to be time, quality and economy of the project depending upon the project needs. In construction project management, the effects of unidentified risks and uncertainties obstruct the project time, quality as well as its economy and upset the project management and thus its development. Identifying the uncertainty and quantitatively analysing the impact on the project performance can notably enhance the exactness, validity and reliability of a project plan. This study describes a methodology to systemize, model, and diminish uncertainty. In essence, Multi criteria decision making model is developed, which is useful for analysing uncertainties even with insufficient information or vague records. The study presents uncertainty assessment methodology based on multi criteria decision making, which is an effective integrated project management tool to deal with a subjective conclusion; that is used to configure a large number of uncertainties. It included a questionnaire survey; based on the data obtained, the probability of factors causing uncertainties were quantified using importance index and multi criteria decision making. The study is to suggest a decision support tool to quantify the probability of uncertainties in construction projects by using importance index incorporated with multi criteria decision making. Using this theory an uncertainty assessment model was suggested. The developed model can be utilized by the construction practitioners like contractors, consultants and clients while critical decision making.

    Review on simulating uncertainties in construction projects
    (International Advanced Research Journal in Science, Engineering and Technology, 2018-02) Katrekar, Shweta (16CEM06); Magar, Rajendra; Khan, Afroz
    Uncertainty certainly affects the performance of a construction project. The exact definition of risk and uncertainty is still not known. Everyone has their own perspectives. Though, it is accepted as the results and outcomes are likely to differ from expected values. The values can be considered to be Time, Quality and Economy of the project depending upon the project needs. Therefore, in construction project management, the effects of unidentified risks and uncertainties hamper the project time, quality as well as its economy and ultimately obstruct the project management and thus its development. Identifying the uncertainty and quantitatively analyses the impact on the project performance can notably enhance the exactness, validity and reliability of a project plan. This paper describes a methodology to systemize, model, and diminish uncertainty. Uncertainty management is one of the major problems faced in construction. Most of the solutions aim to solve the problem but it has to meet demands of all project criteria. The uncertainty is always evaluated at the start of the construction project but it should be continuing process with solutions at the time of whole project life cycle. The application of risks and uncertainties management is practiced in construction in developing countries and thus the result poses massive challenges in the project development and management. Therefore, this study provides a brief idea of various research taken place to simulate the identified uncertainties in construction projects. It also recommends the idea of uncertainty and risk and their consequences on construction projects management as one of the challenges faced in the construction industry of developing countries.
