Design and simulation of proposed automation system in existing manufacturing work environment

The manual operation may impact fluctuation in daily productivity. Manual processing also lead to increase in the number of queues, poor management of Work in Process (WIP) resulting in that impact low productivity. The objective of this project is to propose an automation system that would improve productivity on actual manufacturing assembly area and validate the proposed system with maximize headcount utilization. This project develop modelling of the production system was performed using through ARENA simulation software that evaluates the impact of manufacturing productivity before and after the implementation of the proposed automation system improvement. The system simulation development will be based on assembly processt at PHN Industry, USJ. The main results showed that productivity has improved by 39% due to changes in implementation of conveyor system as part of the automation development based on simulation study. This validates the changes to the work process flow through a simple conveyor system to replace MHS. Further improvement on the simulation process in areas such as queue analysis on the time and number of parts waiting time could add greater complexity to the model resulting in increased of productivity

Data-Driven Decisions and Actions in Today’s Software Development

Today’s software development is all about data: data about the software product itself, about the process and its different stages, about the customers and markets, about the development, the testing, the integration, the deployment, or the runtime aspects in the cloud. We use static and dynamic data of various kinds and quantities to analyze market feedback, feature impact, code quality, architectural design alternatives, or effects of performance optimizations. Development environments are no longer limited to IDEs in a desktop application or the like but span the Internet using live programming environments such as Cloud9 or large-volume repositories such as BitBucket, GitHub, GitLab, or StackOverflow. Software development has become “live” in the cloud, be it the coding, the testing, or the experimentation with different product options on the Internet. The inherent complexity puts a further burden on developers, since they need to stay alert when constantly switching between tasks in different phases. Research has been analyzing the development process, its data and stakeholders, for decades and is working on various tools that can help developers in their daily tasks to improve the quality of their work and their productivity. In this chapter, we critically reflect on the challenges faced by developers in a typical release cycle, identify inherent problems of the individual phases, and present the current state of the research that can help overcome these issues

Urbanization of Information Systems as a Trigger for enhancing Agility: A State in The Tunisian Firms

Nowadays, the information Systems (IS) became one of the main assets of modern corporations, but it faces many problems. Among the most important are low productivity and a large number of failures like obsolescence, heavier, slower and complexity of applications integration. The problem of low productivity of IS was the product of the software crisis, as indicated by the delayed development and implementation of ISs and accumulation which leads to maintenance problems. Requests for new or improved version of the IS have grown faster than the ability of the Chief Information Officer (CIO) to develop the existing IS. Some reasons are: the increase in the cost of software development and the IT choices of the CIO. All the above problems are further exacerbated by the growing complexity and size of software products. The IS is obliged to overcome these difficulties and ensure its evolution. To do this, urbanization is a framework that aims to simplify the IS, to improve communication between its components and to ensure its evolution. In an exploratory approach, this study examines the concept of urbanization studying its impact on the IS to ascertain agility. This was done in order to ascertain the evolution of IS and guarantee the agility facing the environment turbulence. The general assertion is that the Urbanized Information Systems (UIS) changes a firm vision because its procure flexibility, reactivity and interoperability of UIS. The originality of this paper is to explore IS urbanization considered as a French framework of Enterprise Architecture (EA), this study is an empirical validation of the agility of UIS.

Agent-based simulation of open source evolution

We present an agent-based simulation model developed to study how size, complexity and effort relate to each other in the development of open source software (OSS). In the model, many developer agents generate, extend, and re-factor code modules independently and in parallel. This accords with empirical observations of OSS development. To our knowledge, this is the first model of OSS evolution that includes the complexity of software modules as a limiting factor in productivity, the fitness of the software to its requirements, and the motivation of developers. Validation of the model was done by comparing the simulated results against four measures of software evolution (system size, proportion of highly complex modules, level of complexity control work, and distribution of changes) for four large OSS systems. The simulated results resembled the observed data, except for system size: three of the OSS systems showed alternating patterns of super-linear and sub-linear growth, while the simulations produced only super-linear growth. However, the fidelity of the model for the other measures suggests that developer motivation and the limiting effect of complexity on productivity have a significant effect on the development of OSS systems and should be considered in any model of OSS development
