How does the Minit- Lube operations strategy provide competitive advantage? According to the text‚ the 10 decisions of operations management are: 1. Design of goods and services 2. Managing quality 3. Process and capacity design 4. Location strategy 5. Layout strategy 6. Human resources and job design 7. Supply- chain management 8. Inventory‚ material requirements planning‚ and JIT ( just- in- time) 9. Intermediate and short- term scheduling 10. Maintenance

1.0 BASIC CONCEPTS 1.1 What is a Process? In computing‚ a process is an instance of a computer program that is being executed. It contains the program code and its current activity. Depending on the operating system (OSf a process may be made up of multiple threads of execution that execute instructions concurrently (Robbins‚ Kay. A. and Steven Robbins‚ 1996). A computer program is a passive collection of instructions; a process is the actual execution of those instructions. Several processes

system is known as a process. Associated with a process is the current status of the activity‚ called the process state. This state includes the current position in the program being executed (the value of the program counter) as well as the values in the other CPU registers and the associated memory cells. Roughly speaking‚ the process state is a snapshot of the machine at a particular time. At different times during the execution of a program (at different times in a process) different snapshots

time in a useful manner. A single-threaded process‚ on the other hand‚ will not be capable of performing useful work when a page fault takes place. Therefore‚ in scenarios where a program might suffer from frequent page faults or has to wait for other system events‚ a multi-threaded solution would perform better even on a single-processor system. 4.4 Which of the following components of program state are shared across threads in a multithreaded process? a. Register values b. Heap memory c. Global

Paging is solution to external fragmentation problem which is to permit the logical address space of a process to be noncontiguous‚ thus allowing a process to be allocating physical memory wherever the latter is available. 3. Explain the concept of the batched operating systems? mb iti In batched operating system the users gives their jobs to the operator who sorts the

technique is that the auditor does not have an assurance that the program tested is the same program used by the client throughout the accounting process. . In order to overcome this disadvantage‚ the test data technique can be extended to an integrated test facility (ITF) An integrated test facility (ITF) creates a fictitious entity in a database to process test transactions simultaneously with live input. It can be used to incorporate test transactions into a normal production run of a system.
