Quality function deployment (QFD) is a useful analyzing tool in product design and development. To solve the uncertainty or imprecision in QFD, numerous researchers have applied the fuzzy set theory to QFD and developed various fuzzy QFD models. Three issues are investigated by examining their models. First, the extant studies focused on identifying important engineering characteristics and sel...

One of the most common tools for achieving optimization and adequate production process management is linear programming (LP) in various forms. However, there are specific cases application when implies several potential solutions instead one. Exactly such a problem solved this paper, which integrates Multi-Criteria Decision-Making (MCDM) model. First, was applied to optimize lying on line segm...

Recently, the notion of a three-way fuzzy set is presented, inspired by basic ideas decision and various generalized sets, including lattice-valued partial intuitionistic etc. As new theory uncertainty, it has been used in attribute reduction as control method for water level. However, an extension decision, this not multi-criteria making (MCDM short). Based on previous work, paper, we present ...

Effective movement of raw material, semi-finished and finished products plays an important role in successful operation of any manufacturing organization. Material movement from one workstation to another accounts for about 30 to 40% of the cost of final product. Proper methods adopted for material movement are also important for the overall safety of the personnel involved in the manufacturing...

Carbon Fiber Reinforced Polymer (CFRP) is Repair of reinforced concrete structures and both are used for reinforcement One the composite materials. with carbon fibres an advanced non-metal made resin compound, which high strength, Weight loss, itching excessive fatigue It has many excellent performances like resistance. fiber polymer best specific machine properties, so these products High such...

Abstract Zadeh introduced fuzzy sets to study imprecision in real life after which many generalizations have been developed literature. Fuzzy numbers is the major research area of because its needfulness for modeling qualitative and imprecise continuous transitions. Most time, data involved multi-criteria decision making (MCDM) will be form due deforming criteria. Different methods defining tot...

Steel is one of the most powerful industries globally, and associated products have a tremendous impact on nurturing sustainable society. Considering environmental concerns within this industry's supply chain highly successful in saving both energy natural resources lowering greenhouse gas emissions. In light this, suppliers are considered input partners who play specific role business operatio...

The current study set to extend a new VIKOR method as a compromise ranking approach to solve multiple criteria decision-making (MCDM) problems through intuitionistic fuzzy analysis. Using compromise method in MCDM problems contributes to the selection of an alternative as close as possible to the positive ideal solution and far away from the negative ideal solution, concurrently. Using Atanasso...
