This study proposes a system using RFID and XBee technology to address and eliminate the problems resulting from human errors in put-away operations. The human errors in such operations are a serious problem that leads to a number of difficulties in production lines and supply-chain. The use of automated verification system in put-away operations in warehouses is rather rare. Therefore, the study draws from Information Technologies. Three modules - warehouse, racks, and forklifts - have been designed to ensure automated verification of error-free placement of goods. Also, a user interface is developed in Visual Studio C#.Net and SQL server is used for database management system. The developed system also provides monitoring of all steps of operation and enables real-time checking and supervision. Thus, it offers a reliable and transparent operation system, significantly contributes to effective management of supply chain and helps to improve high quality of fast and correct product delivery by minimizing the human errors. Thus, the study highlights the importance of automated verification system for an effective management of supply chain practices by establishing coordination among rack, forklift, warehouse modules, operator and product.

In this manuscript, an Economic production quantity (EPQ) model have been formulated for deteriorating items under partial trade credit policy with crisp and fuzzy demand. For fuzzy demand we take demand as a triangular fuzzy number & we consider upper α 1 − cut & lower α 1 − cut of this fuzzy number. Then the annual inventory cost of retailer is divided into two parts upper α 1 − cut of annual inventory cost & lower α 1 − cut of annual inventory cost. We use weighted sum method to convert multi objective to a single objective. Here we have to derive optimum cycle time so as to minimize the total average cost. Numerical examples are used to illustrate all results obtained in this paper. Finally the model is solved by Generalized Reduced Gradient(GRG) method and using LINGO(12) software.

Through a detailed analysis of the theoretical basis for MOOCs in terms of educational learning theories, this paper attempts at finding the corresponding relationship between the theories and MOOCs, which not only theoretically explains the reasons why MOOCs exceed all the previous education models, but also empirically proves it with voluminous facts and data. The author conducts this research in the hope of enlightening the online education platform of other types. Besides, this paper provides the model framework and strategy to multidimensional educational review based on MOOCs. The model and strategy are applicable not only to MOOCs, the large-scale online education, but also to various online education platforms.

This paper presents a multi-level approach for self-organization of in cyber-physical system resources. Cyber-physical system consists of physical part and cyber part. For implementation of joint actions by devices in physical part, they have to interact in cyber part. It is proposed to use the smart space technology for exchange information between these devices in cyber part of cyber-physical system. Smart Space -- is a computational environment consisting of multiple heterogeneous services (electronic and computational devices, Internet pages, data based, etc.) which has intelligent behavior, can proactively provide information taking into account current situation. Smart spaces allow unifying different levels of services, implement self-organization of services in each level, and providing politics from upper to lower level. Self-organization on every level is implemented based on ontology-based context management techniques and ontology matching method that provides semantic interoperability between interacted robots. Discussed in the paper case study solve the task of self-organization three types of robots based on politics from operation planning services and context situation in smart space. For the scenario implementation the Smart-M3 information sharing platform is used. It provides easy-to-use interfaces for information sharing through the RDF ontologies and publish / subscribe mechanism for connected services.
