This paper builds on a previously proposed approach where fuzzy logic is used to incorporate linguistic variables in system dynamics modeling. The motivation for this approach is to include vague yet dynamic variables that are combined in a meaningful way. The essence of our approach requires the definition of membership functions as representations of the degree to which specific variable attr...

Fuzzy regression models have been applied to operational research (OR) applications such as forecasting. Some of previous studies on fuzzy regression analysis obtain crisp regression coefficients for eliminating the problem of increasing spreads for the estimated fuzzy responses as the magnitude of the independent variable increases; however, they still cannot cope with the situation of decreas...

An inventory model of deteriorating seasonal products with Maximum Retail Price (MRP) for a wholesaler having showrooms at different places under a single management system is considered under random business periods with fuzzy resource constraints. The wholesaler replenishes the products instantaneously and earns commissions on MRP which vary with the ordered quantities following All Unit Disc...

Finding movements of lip for distinction of numbers are one of the functions of image processing and for achieving to this purpose. First, the input image was received by camera and it’s being developed for it’s processing by applying some filters and by using of gray criterion and measure that is on the base of green spectrum and then segmentation of pieces is being carried out on the image by...

Laser metal deposition (LMD) process is an additive manufacturing technique that has attracted the interest of automotive and aerospace industries due to its ability manufacture parts with complex geometries different types metallic materials. However, structure deposited layers geometrical characteristics manufactured are influenced by interaction among parameters. In this paper, fuzzy inferen...

Today, organizations are experiencing problems due to advancements in the environment, community, economy, and technology. In future, physical virtual systems, including whole chain from product design distribution customers feedback will be required overcome for organizations. Thus, companies need comprehend apply Industry 4.0. The most frequently encountered situation literature is absence of...
