TL;DR: The purpose of this paper is to investigate a computing schema for the EPQ in the fuzzy sense and finds that, after defuzzification, the total cost is although slightly higher than in the crisp model; however, it permits better use of the EPZ in the crisps arising with little disturbances in the production, and demand.

TL;DR: The purpose of this study is not only to build a structure model of risk in software development but also to evaluate the rate of aggregative risk by fuzzy set theory.

TL;DR: The total cost of the backorder inventory problem with fuzzy backorder is slightly higher than that in the crisp model; however, it permits better use of the economic fuzzy quantities arising with changes in orders, deliveries, and sales.

TL;DR: It is found that, after defuzzification, the total cost is slightly higher than in the crisp model; however, it permits better use of the economic fuzzy quantities arising with changes in orders, deliveries, and sales.

TL;DR: This study proposes two algorithms to tackle the rate of aggregative risk in a fuzzy environment by fuzzy sets theory during any phase of the life cycle by building a group decision making structure model of risk in software development.
