It can improve overall business performance as well as quality of produced parts by decreasing the wastes in processes and resources to increase added values in process of part production. As a result, lean manufacturing can produce advanced manufacturing systems with fewer faults and errors, less waiting, and less complexity in the process of part production. The lean manufacturing systems can be applied to the virtual manufacturing, sustainable manufacturing, supply chain and industry 4.0 in order to enhance the efficiency levels of part production. To manage the resources in the process of part production, knowledge management systems can be applied to the lean production. Advanced assembly lines in the automotive and ship industries can be generated in order to decrease the waste time and energy in assembly process of part production. A review of the implementations of lean production techniques in enhancing part manufacturing efficiency is provided and future research works are also suggested. The study's main goal is to provide a beneficial study for researchers in the field by providing an overview of current research on productivity enhancement using advanced lean production systems. It has been discovered that by reading and analyzing current successes in published papers, the research field can be advanced.

The information in the networks needs to be kept secured and safe in order to provide an effective communication and sharing device in the web of data. Due to challenges and threats of the data in networks, the network security is one of the most important considerations in information technology infrastructures. As a result, the security measures are considered in the network in order to decrease the probability of accessing the secured data by the hackers. The purpose of network security is to protect the network and its components from unauthorized access and abuse in order to provide a safe and secured communication device for the users. In the present research work a review in recent development of network threats and security measures is presented and future research works are also suggested. Different attacks to the networks and security measured against them are discussed in order to increase security in the web of data. So, new ideas in the network security systems can be presented by analyzing the published papers in order to move forward the research field.
