Fast development in the utilization of cloud computing leads to publishing more cloud services on the cloud environment. The single and simple services cannot satisfy the users’ real-world complex requirements. To create a complex service, it is necessary to select and compose a set of simple services. Therefore, it is essential to embed a service composition system in cloud computing environment. Service composition is one of the important NP-hard problems in the service-oriented computings. In this paper, a biogeography-based optimization algorithm is used to create the optimal composite-services. The proposed method was simulated and executed on five different scenarios with different number of tasks and candidate services. The throughput of the proposed method, genetic algorithm and particle swarm optimization algorithm are respectively 0.9997, 0.9975 and 0.9994; furthermore, the reliability of these methods are respectively 0.9993, 0.9980 and 0.9982. The results of simulations indicate that the proposed method outperforms the previous methods in the same conditions in terms of throughput, successability, reliability, response time, and stability.

Service-oriented architecture is one of the fields of software engineering that enables a connection between the two systems in a heterogeneous network with different technology. Architectural features include the ability to reuse and agility against future changes. In the service-oriented architecture, one of the most important and fundamental challenge is that despite various code generators that introduced in this field, there are still shortcomings in the various phases of the code generator. In this paper, due to the weaknesses of the code generators in the different phases and that these shortcomings be found in the quality, and production software systems, have to offer a hybrid approach for the introduction of two references to the code generator. In order to use the advantages of the above two code generator, a hybrid code generator (SOG) is offered. Also, in order to increase the efficiency in the production of software systems using the provided code generator, the new features to enhance the security the code generator, increase programming languages supported, multiple formats for the transmission of information between client and server, adding a cryptographic layer and the production of panels for database management is provided on the web. The main objective of this paper is the code generator provides the codes related to service-oriented architecture. In order to assess the ability of the proposed code generator, the code generator is evaluated based on criteria related to different protocols and data transfer between client and server.

To cope with economic constraints, request for mass customization, globalization and cost reduction ... is increasingly enhanced and the development of manufacturing strategies towards a lean manufacturing strategy has gone. Lean strategy deployment in a company, leading to company reorganization in the logical chain of production, will be to avoid waste. In fact, focusing on the business allows the company to share costs and reduce development time, to control the quality of its products. In general, the circulation and flow of the right information in a company, will have an important role in achieving a lean strategy. currently Information Systems of a company consists of multiple software and designed systems. ERP, PLM, SCM , etc., each system designed to achieve the objectives in one aspect of the business. While a variety of products, all of which are required for the company, but Creates redundancy, heterogeneity and the increasing volume of information. This inconsistency can cause big problems in the field of communication inter- company. In this study, a method based on Service Oriented Architecture and Enterprise Service Bus (ESB) will be presented, including the following, and the solution is to solve these problems: 1. Intelligent Routing Module for organize the workshop resources 2. The monitoring & governance module for control on product performance, production and quality 3. mediation module for exchange data between different transactions in business and technology 4. The dynamic choreography module to combine and arrange the services action to achieve a particular goal in Industrial Services
