Realization of international commodity flows is prerequisite of economic development. Organization of international commodity flows is a very complex and responsible task. Freight forwarders and logistics providers are architects of mentioned flows. They have to coordinate a large number of processes and executors in a synchronized chain. For that reason, they must have multidisciplinary knowledge to make this possible. However, the realization of a large number of activities and the presence of a various participants are accompanied by numerous risks and problems. They can endanger the flow and greatly slow it down. In this paper freight forwarders risks in the process of organization of international flows are analyzed. For risk analyses FMEA approach, as one of the most frequently used approaches is used. The most important risks in the processes of preparation and goods loading, export clearance, documents preparation, transport, import clearance, unloading, cost calculation and payment are identified. According results the most important risks are: wrong loading (unloading) address, taking incomplete (unchecked) documentation, bad communication (lack of information), traffic congestion, congestion on the border and customs offices, bad anticipation of unexpected costs. Each risk is characterized by certain parameters important for corrective and preventive actions. In the observed example it was found a great applicability of the FMEA approach.

“…Natural language information analysis method and object role modelling have been applied in creating symbolic fuzzy models representing customer knowledge in a defect recognition system (Bombardier et al, 2007). Definition of membership functions and values captured from human experts, can also be represented using MATLAB fuzzy logic toolbox simulator (Celikyilmaz & Turksen, 2008;Guimaraes & Lapa, 2007;Jafelice et al, 2009). One of the challenges of fuzz rule-based system development is the lengthy process of rule elicitation and every procedure is specific to each application (Banerjee et al, 2001) .…”

A system which represents knowledge is normally referred to as a knowledge based system (KBS). This article focuses on surveying publications related to knowledge base modelling and manipulation technologies, between the years 2000-2015. A total of 185 articles excluding the subject descriptive articles which are mentioned in the introductory parts, were evaluated in this survey. The main aim of this study is to identify different knowledge base modelling and manipulation techniques based on 4 categories; 1) linguistic knowledge base; 2) expert knowledge base; 3) ontology and 4) cognitive knowledge base. This led to the proposition of 8 research questions, which focused on the different categories of knowledge base modelling technologies, their underlying theories, knowledge representation technique, knowledge acquisition technique, challenges, applications, development tools and development languages. A part of the findings from this survey is the high dependence of linguistic knowledge base, expert knowledge base and ontology on volatile expert knowledge. A promising technique for knowledge-based business management and other knowledge related applications is also discussed.

“…In the fuzzy FMEA literature, the studies have mostly concerned with the fuzzy rule-base approach by using if-then rules 3,7,15,16,17,20,21,22 . After the assignments of the linguistic terms to the factors, if-then rules were generated taking the linguistic variables as inputs to evaluate the risks.…”

Process Failure Modes and Effects Analysis (PFMEA) concept, has been developed based on the success of Failure Modes and Effects Analysis (FMEA) to include a broader analysis team for the realization of a comprehensive analysis in a short time. The most common use of the PFMEA involves manufacturing processes as they are required to be closely examined against any unnatural deviation in the state of the process for producing products with consistent quality. In a typical FMEA, for each failure modes, three risk factors; severity (S), occurrence (O), and detectability (D) are evaluated and their multiplication derives the risk priority number (RPN). However there are many shortcomings of this classical crisp RPN calculation. This study introduces a fuzzy hybrid approach that allows experts to use linguistic variables for determining S, O, and D for PFMEA by applying fuzzy 'technique for order preference by similarity to ideal solution' (TOPSIS) and fuzzy 'analytical hierarchy process' (AHP). An application to a spindle manufacturing process expresses the relevance of the fuzzy hybrid model in PFMEA.
