Advantages And Disadvantages Of Manual Inventory Management

Inventory management is an integral part of businesses. There are manual and automated management systems each one having its own advantages and disadvantages. Problems with manual system need to be analyzed, and take steps to consider to see if an automated system is more feasible for the business. The business process assessment needs to be in the equation as well as software capabilities and hardware needs. INVENTORY MANAGEMENT Most businesses, regardless of their size, small or large, carry inventory. The inventory can be from raw material to finished products, but it needs to be counted and tracked manually or with an automated system. Regardless of the system used, it is important to maintain stock at the right levels as well as†¦show more content†¦There are also disadvantages with the manual inventory system. It can be labor intensive to run by having to constantly monitor the inventory every time a sale takes place to ensure that stocking levels are appropriate. Prone to human errors is another disadvantage of the manual inventory system. The manual inventory system relies on people s efficiency to record the sale in a timely manner and to count the items correctly to avoid increasing inventory levels and its carrying costs, or not having enough product on hand to fulfill an order. Some of the carrying cost to consider are warehousing storage, insurance, taxes, depreciat ion, and breakage among others.  © Fishbowl Inventory A business owner wanting to convert a manual inventory system to an automated system must have detailed processes that take place with the current system and then begin to change it to what he or she wants it to be. With the new system design, employees performing the current tasks regularly, need to be included in the new designing process. A thorough business process assessment must be done to be able to assess the business process efficiently. The report should list all aspects of the business, requirements and trade demands as well, to measure its processes effectively. Any processes happening behind the scenes need to be account and make changes necessary to the procedures to ensure the process is complete.

Cyber Attacks And Its Effects On The United States

Most ISIS practice customs from the 7th century, but the methods they use to fight a war are 21st century techniques. ISIS have an advanced computer network that uses social media to attract terrorists worldwide to help them attack countries like the United States. Many countries have been victims of cyber attacks but may not realize it until long after the security breach occurred. In June of 2015, the Office of Personnel Management found out that it was being hacked. The hack had been going on for several months before authorities realized it. It was one of the largest security breaches in United States history. With the news of security hacks finally reaching the public, many people question the government and wonder if it can adequately protect itself from future attacks. The attacks from ISIS are making people feel uncomfortable and unsecure. Many people are beginning to realize how serious the ISIS and their online schemes are. â€Å"The United States of America is under atta ck,† warned Rep. Elijah Cummings during a House Oversight and Government Affairs Committee hearing in June of 2015. (Law Street) Katherine Archueta is the director of OPM. She faced a lot criticism at the hearing for not updating the databases, because she was already aware of the security issues.

Keywords: automaton operator, kinematics, kineticss, feedforward control. 1 Introduction Motivation and history of industrial automaton Today, we can run into industrial automaton in many mills in the universe. Applications of industrial automatons include welding, picture, choice and topographic point ( packing or SMT line ) , production review, and proving. Harmonizing to the International Federation of Robotics ( IFR ) , by the terminal of 2011, there were at least 1,153,000 operational industrial automatons. And IFR estimated the world-wide gross revenues of industrial automatons about US $ 8.5 billion. If cost of package, peripherals and systems technology are included, the industrial automaton market was estimated US $ 25.5 billion in 2011. Therefore, industrial automaton has been become an interesting field. Along with development of industrial automaton, simulation and theoretical account of industrial automatons are of import. They can supply a batch of utile information for many intents such as layout rating, kinematic, dynamic survey, off-line scheduling to avoid obstruction in the undertaking infinite and design mechanical construction of automatons. The history of industrial automaton has associated with the development of computing machine aided design ( CAD ) and computing machine aided fabrication ( CAM ) systems. In 1954, George Devol applied for the first robotics patents ( granted in 1961 ) . In 1956, Devol and Joseph F. Engelberger formed the world’s foremost robot company was Unimation which was based on Devol’s original patents and Engelberger has been called as the male parent of robotics. Unimation has been built with hydraulic actuators and programmed in joint co-ordinates. The angle of each articulation was stored during a teaching stage and replayed in operation. In the 70s the automaton industry increased really rapidly because of the tremendous investings by the automotive industry. In Europe, ABB Robotics and KUKA Robotics brought automatons to the market in 1973. ABB Robotics introduced IRB 6, it was become the first commercially operator which controlled all electric by micro-processor in the universe. The first two IRB 6 automatons were installed in production for crunching and smoothing pipe decompression sicknesss in 1974. In 1973 KUKA Robotics built its first automaton, FAMULUS, besides one of the first articulated automatons have driven six electromechanically axes. In US, many US companies entered the field, including elephantine companies such as General Electric, and General Motors ( a joint venture formed by General Motors and FANUC LTD of Japan called FANUC Robotics ) . Other companies besides started robotics concern such as Automatix and Adept Technology, Inc. In 1984, Unimation was acquired by Westinghouse Electric Corporati on for 107 million U.S. dollars. After that Westinghouse sold Unimation to Staubli Faverges SCA of France in 1988, which is still doing articulated automatons for general industrial and cleanroom applications and even bought the robotic division of Bosch in late 2004. Hardware and Software During this thesis, three package ( RecurDyn, SolidWorks, Matlab ) have been used to work out this thesis assignment. Dynamixel servo motor besides was used for experimental intents. RecurDyn V8R2 RecurDyn is developed by FunctionBay, Inc. which is a professional CAE company and provides MultiBody Dynamics ( MBD ) .
