Abstract This kind of study evaluates the most widewpread methodologies obtainable in literature accustomed to measure complexness. The research moves from a theoretical physic perspective, throughout the Complexity Theory, to a manufacturing system. About these topics, two category frameworks are proposed in order to categorize one of the most widespread steps. In particular, the other classification construction regards entropic measures traditionally used to measure complexity in manufacturing systems. With regards to this second framework, two indexes had been selected (static and active complexity index) and an enterprise Dynamic unit was developed. The[desktop] was used with empirical data collected in a job store manufacturing system in order to test the usefulness and validity of the dynamic complex index. The Business Dynamic model assessed the trend from the index in function of numerous inputs in a selected job center. The results demonstrated that the optimum value in the dynamic intricacy index symbolizes the so called " advantage of chaosвЂќ, where the sum of information had to manage the system is maximum and where there is the advantage between versatility and efficiency of the production system. In conclusion, the main end result reached with this study regards the " edge of chaosвЂќ this provides the target construction for a business, in a particular system and under the same external circumstances. Key Words Complexity Measures, Entropic Measures, Making Systems, Job-shop, Business Aspect
1 . Introduction The origins from the studies from the Complexity Theory come from the researches about definately not equilibrium thermodynamical phenomenon completed by Nobel Award Ilya Prigogine [1, 2]. The subsequent studies about complexity took very different guidelines and their development has been hurrying and messy because of their severe multidisciplinary. Something is a complete of associated parts which in turn interact the other person. Therefore , the complexity of any system identifies the number of contacts or affects between the same parts of the system . A " simpleвЂќ system may believe a limited volume of conditions, when a chaotic one may assume an enormous volume of conditions because its parts are spread and they interact freely; this way his actions are absolutely not expected. But a complex system is not really a chaotic system. Particularly, a complex system  is made of a variety of parts, which will possess particular functions. The elements of the program are hierarchically organized and perhaps they are linked by many non-linear connections but the hierarchical structures warranties to keep a kind of control. These types of nonlinear connections make difficult an synthetic approach intended for the explanation of every section of the system, whilst it is necessary an artificial approach pertaining to the comprehension of the entire system. Therefore , a complex system places itself between systems whose actions are simply foreseeable and the topsy-turvy systems. A particular kind of complicated system is a complex adaptive program (CAS) . This sort of system provides another important feature: it changes, learns and evolves getting through " practically equilibriumвЂќ constructions. Complex adaptive systems are characterized by a great emergent tendencies of the elements, in whose behavior stands between predictability and unpredictability. Classical monetary theory details firms because entities in whose target is optimizing solutions utilization and maximizing getting . Moreover, an organization: в€’ Is aware of all available techniques, elizabeth. g. almost all possible combos of input and output; в€’ Understands its own creation...
