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...

The paper focuses on the identification and resolution of conflicts and contradictions in complex systems. By constructing simple, computerbased bottom-up models of an exemplar complex system, we show the potential for the emergence of multi-phase macro-level outcomes. We then show how these discontinuous phase-shifts may be modelled as contradictions, and from there, how TRIZ tools can be used...

This paper describes design principles that were extracted from the profiles of products redesigned to be more environmentally benign. These extracted principles will be used to support the work of creating a Design for Environment (DfE) methodology called ENVRIZ that provides product designers with a procedure for creating more environmentally benign products and overcoming environmental contr...

In order to increase their competitiveness, companies need have five important capabilities in the product development process, namely, ability identify customer and environmental requirements, convert them into technical create innovative designs, determine best improvement alternatives. Based on a literature survey, previous studies are still inadequate incorporating these simultaneously effe...
