Step for determine the utility for money :
Develop a payoff table using monetary values
Identify the best and worst payoff value
For every other monetary value in the original payoff table
Convert the payoff table from monetary value to calculate utility value.
Apply the expected utility criterion to the utility table and select the decision alternative with the best expected utility.

ERP integrates business of an organization through a centralized database. The organizational data and transaction data are stored in the database. This data is a rich source of information. There are many software tools that would process the data and discover useful patterns. These techniques are referred to as data mining. The data from an ERP system may not be directly usable by data mining tools. The data may have to be pre-processed and made ready for data mining. A data warehouse is created from the ERP data that makes the data ready for data mining. An organization needs to interact with their suppliers for obtaining the raw material or semi-finished goods. They also need to interact with their retailers and dealers. These interactions may happen using EDI technology. Supply chain management (SCM) refers to managing suppliers and retailers. Customers are the reason why a business exists. The focus has changed from providing customer a product to providing a service built around the product. Customer relationship management (CRM) is the technology that helps an organization to manage its customers. CRM and SCM both integrate with ERP system and are collectively referred to as ERP-II.

Engineering Operational Excellence in Every Manufacturing Business Process wi...Catavolt, Inc.
This slideshare describes how manufacturing engineering and research and development teams can utilize mobility for driving operational excellence in business processes throughout the organization.
A problem is provided which is solved by using graphical and analytical method of linear programming method and then it is solved by using geometrical concept and algebraic concept of simplex method.
This chapter aims to provide basic backgrounds of different types of machining processes and highlights on an understanding of important parameters which affects machining of metals with their chip removals.
Metal cutting or Machining is the process of producing workpiece by removing unwanted material from a block of metal. in the form of chips. This process is most important since almost all the products get their final shape and size by metal removal. either directly or indirectly.
The major drawback of the process is loss of material in the form of chips. In this chapter. we shall have a fundamental understanding of the basic metal process.

Operational Research and Organizational SystemIJRES Journal
Organizational systems, as well as specific integration of social and technical systems are extremely important for the development of human society. The most part, the problems of managing these systems are reduced to operations research - a generic term for activities that define the processes involved in the functions of organizational systems, and hence the term operations research. Field of study operations research as a scientific discipline, the organizational processes and activities that are being carried out and an important determinant of the intention to find the best decisions in managing the operations undertaken to achieve the set goals of the system. The generality of operations research is reflected in the fact that apply to all types of organizational systems - commercial, industrial, agricultural, military, medical, educational, government, and the like. Users of operations research decision makers - managers, whose task is to efficiently and effectively manage organizational systems. In this paper we consider operational research and conceptual foundations that enable its effective use in solving the problem of organizational systems.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. What is operations research?
Operations Research is an Art and Science.
The British/Europeans refer: "Operational Research".
The Americans refer: "Operations Research".
Modern synonyms: Management Science (MS) | Decision Science
(DS)| Industrial engineering" (IE)
It is often considered to be a sub-field of mathematics.
The Americans are using terms OR and MS together: "ORMS".
ORMS: Operations Research Management Science
3. OR had its early roots in World War II.
OR had provided solutions to
Military operations during World
War II. .
4. Operations Research?
Operational Research is the discipline of applying advanced
analytical methods to help make better decisions.
OR is professional discipline.
It deals with scientific methods.

Operations Research Society, America: “Operations research is
concerned with scientifically deciding how to best design and
operate man machine systems usually requiring the allocation of
scare resources”.
