Increasing demand for simplification of frequently used products promotes innovation with simple mechanisms. In this study, an attempt is made by amalgamating FMEA, QFD, TRIZ, LCA, and fuzzy TOPSIS the development sustainable products. The methodology executed to redesign a pressure relief valve (PRV) in economic, sustainable, innovative manner. failure modes PRV are considered FMEA ranked thei...

Modular design, Axiomatic design (AD) and Theory of inventive problem solving (TRIZ) have been increasingly popularized in concept modern mechanical product. Each method has their own advantages drawbacks. The benefit modular is reducing the product period, AD capability analysis, while TRIZ’s expertise innovative idea generation. According to complementarity these three approaches, an systemat...

TRIZ can be considered as specific problem solving approaches. It uses among others concepts like problem and systems. This paper is a trial to describe with general tools of system and problem modelling how model of problem and model of system evolves through ARIZ process or at least through some of it steps. The purpose of this article is to show that problem solving, and particularly, proble...

a supply chain is composed of a complex sequence of processing stages, ranging from raw materials supplies, parts manufacturing, components and end-products assembling, to the delivery of end products. in the context of supply chain management, supplier selection decision is considered one of the key issues faced by operations and purchasing managers to remain competitive. therefore, requiremen...

هرمنوتیک فلسفی یکی از نظریات تفسیر متون در غرب پس رنسانس است که تحولاتی را تفکر معرفتی برخی نواندیشان مسلمان ایجاد نمود. این نظریه افزون بر اختلاف مبانی و اصول، سبب نسبی‌گرایی پلورالیسم تفسیری می‌شود. اندیشمندان حوزة قرآن کریم با غفلت پیامدها پذیرش سعی تطبیق مسئلة پایان‌ناپذیری فهم دارند، بنابراین تحلیل مقایسة دو ضرورت دارد. پژوهش هدف انتقادی روش تحلیلی- تطبیقی درصدد بررسی مؤلفه‌های تفاوت آن اس...

The ultimate goal of Patternless Casting Manufacturing (referred to as PCM) is how to obtain the casts by casting the sand mold directly. In the previous PCM, the resin content of sand mold is much higher than that required by traditional resin sand, so the casts obtained are difficult to be sound and qualified products, which limits the application of this technique greatly. In this paper, the...
