The function-structure (F-S) Map expresses the high-level structure of a design. It is often used in the early stage of conceptual design and serves as the starting point for a number of design tools like quality function deployment, failure mode and effects analysis, and more. On the other hand, in designing risk products whose failure can result in serious damage to the quality of human health or the society, the designer often uses tools like failure mode and effect analysis or fault tree analysis to detect weaknesses in design before the products are shaped. Failures, nonetheless, take place and cause negative impact to the society. It is then that the designer or other experts review the design to find flaws in the failure analysis tree or find elements or links in the graph that the designer overlooked. In other words, pre-production failure analysis is limited to the designer’s knowledge and insight. This paper proposes a way to make use of failure knowledge with past accident cases by constructing the F-S Map for the failed products and storing the information in a failure database. Designers can then compare the F-S Map for new products with linked representation of past failure cases and realize scenarios of failure he did not recognize or have to design carefully.

Service Blueprint

Nowadays, shoes are not just a casual footwear. Certain shoes can tell the social class of a person. The increase of shoe prices and social status of wearing expensive shoes became a trigger for the development of shoe laundry services. There were a service quality problems in a shoe laundry in Tangerang, Indonesia. Several methods to improve service quality was studied and it is decided to propose a new model, which is integration model of Service Blueprint, Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA). The research starts with identifying the problem with observation and interview, then build Service Blueprint. Based on the fail point that has been identified in Service Blueprint, the FMEA used to find which process is the most dominant cause of failure and the most urgent for improvement. The next step is using FTA to find the root cause of the failure of the dominant cause. After analyzing the FTA, the improvement was proposed and implemented. Service failure before and after implementation was compared to see the improvements. There are 6 suggestion and implemented. After the implementation, the error in each process was measured and it is found a decrease in error in each process.

Nowadays,improving the quality of products, reducing cost and meeting customer’srequirements are necessary to shorten the time of new product development(NPD). NPD is used to describe the complete process of bringing a new product to market and conceptual design process(CDP) is at its early stage and has mostly changed from passive respond toaggressive one. Thus, this study proposed a practical method for CDP in NPDthrough three phases as Converting customers’ requirements to product specifications,Generating and selecting of concepts and Testing and finalizing the concepts byusing some different management-engineering techniques. Firstly, this papertried to prioritize customer’s requirements related to product by AHP (AnalyticHierarchy Process) and convert them to engineering parameters of TRIZ (Theoryof Inventive Problem Solving) in order to define the inventive principals.Next, based on QFD (Quality Function Deployment), we measured the weight valuesof inventive principals. Finally, as FMEA (Failure Mode and Effect Analysis)can analyze the weight values and reduce the sequential risk, then finalconceptual design was generated. At the end, a medical glasses was used as acase study of innovative design to validate the method and explain how thestrategies of this research for CDP.

Fmea Method

The paper aims at presenting the FMEA method based on the fuzzy technique, representing a new approach to the failure analysis and its effects on the observed system. The FMEA (Failure Mode and Effect Analysis) method has assigned the risks a coefficient i.e. a numerical indicator that very clearly defines the degree of risk. The risk is calculated as a mathematical function of RPN which depends on the effects S, probability O that some case will lead to a failure and to a probability that a failure D can not be detected before its effects are realized. RPN = S O D. The FMEA method, based on the fuzzy logic, makes a more reliable evaluation of the observed system failures possible.

Prevention Methods

A good quality control system is important to be implemented to increase productivity and minimize defects in products. One of the quality control methods is failure mode and effect analysis (FMEA). This study uses the FMEA to identify the causes of the defects and recommend the prevention methods to overcome the causes of the defects in an Indonesian paper mill. The risk priority number (RPN) is calculated by multiplying the severity, occurrence, and detection of the failures that have been determined. Unsymmetrical and tainted products are the most dominant defects in the paper mill. An inappropriate machine setting is the cause of unsymmetrical products with the highest RPN of 343. The second highest RPN is problems with bleaching machines that caused tainted products with an RPN value of 216. This study offers suggestions to Indonesian paper mill to prevent and minimize defective products.

<span class="fontstyle0">A company should pay attention to operational risk to maximise its efficiency and effectivity.<br />Identification of failure and the cause and the impact of the failure at milling station is needed to be done so that the sugar production process can run well. Here, we employ a failure mode and effect analysis to identify the failure and its effect. We obtain 22 operational risks with two critical risks. The two critical risks are then used as top event in analysing the cause of the failure. The result from fault tree analysis shows that there are 4 basic events, which are the turbine vibrates, schedule part’s change before failure, high rainfall and the schedule and priority of processing</span>
