Logistics Process

Construction logistics process hides some non value added activities which are difficult to avoid, those activities have extended leading time which are not only cause the delay of the project completion, but also spend more production expenses that effect to the profit itself. Data rising by questionnaire is conducted in 22 qualified contractors around Denpasar with 3 respondents in each contractor. Data raising by questionnaire is done in 2 stages, first stage is questionnaire which identify wastes. Second stage are questionnaire which determine waste causes. Field observation is aimed to create a value steam mapping of construction logistic process. It had been found 7 types of wasting which often occurs. They are the field inspection, the purchase of one type material in different suppliers, awaiting the instruction of the owner, the delay of the material transportation, the purpose of approval or additional signature, clarification needs, awaiting the instruction of the superior. Afterwards, the cause of each wasting, namely the workers inspected are less skilled, the bad quality of goods given by the suppliers, the owner procedures which require workers await the instruction before working, material loading-unloading and distribution process is too slow, a complicated bureaucratic system and unclear information. And from the observation, it is obtained that there are some non-added activities occurred throughout the value stream of the construction project logistics, among them awaiting the approval of the supervisors, transportation, awaiting the order process which is still done manually and product defects during the material selection. As a wasting reduction, it is necessary to simplify the process, create a standard operation procedure, provide enough training to the workers so they are more independent, use an information technology to ease the delivery of the report, hold a long-term contracts with the suppliers and the internal customers.

Industry 4.0 implies sustainable production by providing green products created through environmentally responsible processes. This paper aims to analyze the two main business processes responsible for energy innovation in a telecommunications company: “develop property strategy and long-term vision” and “evaluate environmental impact of products, services, and operations”. The processes will be introduced using an initial set of key-performance indicators (KPIs) and American Productivity & Quality Center (APQC) Process Classification Framework activities. Through value stream analysis, the non-value-added activities will be eliminated. Ultimately, to provide an overview for the stakeholders, a new set of KPIs will be proposed and the processes will be modeled using Event-Driven Process Chain (EPC) and Suppliers-Inputs-Process-Outputs-Customers (SIPOC) methods.

The development of pottery products was emphasized as the research and development project. The main ingredient was Nong Suea clay, Pathumthani province. Normally, Nong Suea clay was used for land-fill industries. However, the way to use Nong Suea clay as materials for pottery products could be a value added technology. In addition, the pottery products created from Nong Suea clay were used as the decorative materials. From the line blend method, six mixing ingredients were focused. The researcher found that the suitable mixing ingredient was the third formula that contained Nong Suea clay (80%) and Ranong white clay (20%). This formula was processed into five types of pottery products. Two temperatures were monitored for firing. First, the temperature at 850 °C was used for three different types of pots. This product was normally shaped by hand with a throwing wheel that led to the industrial process level. Second, the temperature at 1,200 °C was used for two different types of vases. The product decorations of these groups were applied by the flowing glaze technique which was suitable for long-term research and development. The craftmen in should be highly skilled, tool uses, and higher temperature capacity of kiln.

<span>The burden of a value-added tax is distributed each time the ownership of merchandise changes as the merchandise moves down-stream through distribution channels to consumers. Other things being equal, the burden of the tax on retailers or other vendors purchasing merchandise for resale is determined by the markup rule chose by retailers or other vendors. Given the markup rules discussed, a fixed-percentage markup is shown to minimize the value-added tax burden on firms purchasing merchandise for resale.</span>

Deploying femtocells has been taken as an effective solution for removing coverage holes and improving wireless service performance in 3G-beyond wireless networks such as WiMAX and Long Term Evolution (LTE). This article investigates a novel framework of dynamic spectrum management for femtocell networks, called cognitive-empowered femtocells (CEF), aiming at mitigating both cross-tier and intratier interferences with minimum modifications required on the corresponding macrocell network. With the proposed framework, each CEF base station (BS) and the femtocell users can utilize spatiotemporally available radio resources for the access traffic. We conclude that the proposed CEF framework can effectively complement the existing femtocell design and serve as a value-added feature to the state-of-the-art femtocell technologies, while achieving high scalability and interoperability by minimizing the required modifications on the macrocell protocol design.
