This paper describes the proposal of Poka Yoke Roller Coaster (PKYC) jig as a device to detect nut weld missing of door patch base line model (BLM) at assembly line station. The PKYC was proposed in order to detect nut weld missing problem and to reduce cycle time and manpower that lead to higher cost by applying quality management concept as a problem-solving tool. This special purpose tool was capable to meet specific job based on industrial need by providing repeatability, interchangeability and accuracy in the manufacturing of products. A Quality Control (QC) approachcalled the Zero Quality Control (ZQC) was used to achieve zero defects at production line. In order to reach zero defects, poka yoke method was applied in this research. Outcomes indicate that PKYC can be utilised as a custom-tailored jig for detecting nut weld missing as well as fulfilling other objectives.

Current Case

Assembly line balancing is assumed to have fixed task within specified task time during the initial stage of the mass production. The problem of current case study of this assembly line was the production line cannot meet the expected output plan with imbalance station cycle time. In this paper, productivity study and line balancing is applied to improve production line of GGMG & CALICO. The desired cycle time defined using the Standard Time Data (STD) which required the person to perform assign task till completion by defining the performance rating of person. The proposed solution proved by the implementation analysis conducted in the research. The results showed that the productivity of production line which is tremendously increased within 50% after implementation. There are six factors identified during the study which are bottleneck stations, workpiece flow, line layout, ergonomic, resource assignment and buffer allocation.

Cold State

Although the quality of a completed engine ready for shipping is traditionally assured by adopting the firing run at the final process of the engine assembly line, we have still not readily accepted the testing of engines in cold state i.e. without actual combustion & continue to neglect all its long term benefits in view of the immediate shortcomings which not only enhances the inspection speed, fault detection but also poses zilch threat to the environment around us. It increases the effectiveness of the “In-Process Quality Control” of an Engine production line.

Abstract Cold test stations are commonly arranged as sequential processes along a complete engine production line. The production line consists of several stations for engine building purposes, and before the engine exits the production line it passes through different validation and testing stations, such as leak testing stations, piston protrusion stations (known as torque to turn stations), and cold test stations. Each of these stations has a sequence of operation that is performed automatically or semi-automatic with the support of an operator. The waiting time until the engine finishes the operation in one station is called “cycle time”. The longer the cycle time the less efficient the production line. Cold testing stations are considered the most complicated and time-consuming, yet important test stations for engine and powertrain development. The lengthy cycle time affects the overall efficiency of the production line. This paper investigates the problem of the cycle time difference between consequent stations and its effect on the overall efficiency of the factory. New techniques and operations research methods are introduced aiming to recover from such a manufacturing obstacle. This research is investigating the limitations of a manufacturing operation standpoint. Each test station is treated as a block that simulates the actual station, and the overall factory workflow is described. Time-based equations governing block time, idling time, and utilization of the system are introduced, and the factory efficiencies are calculated and compared. After identifying the problem, a practical solution is explained.

Production System Analysis

The paper is focus on the assembly line of the factory .The nodular method and second-watch measuring methods are applied to measure the work time of the bottleneck stations. To improve the cycle time of the assembly line, the work contents of relative stations is reallocated. Finally, the production line is disposed again on the basis of the principle of ECRS and the line balancing theory .After implemented the new method, the capability of this production line has improved.

AbstractThe G8D method is a universal method for solving problems arising in production processes, also used in optimisation of these processes. The method allows the detection and elimination of any drawbacks occurring in manufacturing processes and ensuring the safety of these processes.In the article, the authors have presented one of the sensitive and critical disciplines of the G8D problem solving method in production processes, i.e. discipline D2 - “problem description”. The authors have presented the algorithm of procedure in the discipline D2 as well as the quality management tools that can be used to correctly “describe the problem”. The authors have also discussed the procedure for the discipline D2 in the “problem description” for the case of the projection welding of a nut.

Summary:This guideline is a prerequisite for the quality management in the treatment of non-Hodgkin-lymphomas using radioimmunotherapy. It is based on an interdisciplinary consensus and contains background information and definitions as well as specified indications and detailed contraindications of treatment. Essential topics are the requirements for institutions performing the therapy. For instance, presence of an expert for medical physics, intense cooperation with all colleagues committed to treatment of lymphomas, and a certificate of instruction in radiochemical labelling and quality control are required. Furthermore, it is specified which patient data have to be available prior to performance of therapy and how the treatment has to be carried out technically. Here, quality control and documentation of labelling are of greatest importance. After treatment, clinical quality control is mandatory (work-up of therapy data and follow-up of patients). Essential elements of follow-up are specified in detail. The complete treatment inclusive after-care has to be realised in close cooperation with those colleagues (haematology-oncology) who propose, in general, radioimmunotherapy under consideration of the development of the disease.

AbstractThe tools for quality management are used for quality improvement throughout the whole Europe and developed countries. Simple statistics are considered one of the most basic methods. The goal was to apply the simple statistical methods to practice and to solve problems by using them. Selected methods are used for processing the list of internal discrepancies within the organization, and for identification of the root cause of the problem and its appropriate solution. Seven basic quality tools are simple graphical tools, but very effective in solving problems related to quality. They are called essential because they are suitable for people with at least basic knowledge in statistics; therefore, they can be used to solve the vast majority of problems.
