Just in Time vs. Just in Case

Planning Just-in-Time versus planning Just-in-Case

In this paper we introduce a distinction between two forms of planning: Just-in-Case planning versus Just-in-Time planning. The first refers to the traditional mode of planning as currently practiced in most urban and regional planning agencies, whereas the second, is what planning in a self-organizing system might be. The key notion behind this distinction is Just-in-Time— a method of producti...

Just – In – Time و تأثیر آن بر حسابداری مدیریت

سیستم JIT سیستمی است که انجام به موقع فعالیتها را مورد تأکید قرار می دهد. چنین نگرشی در سیستمهای تولیدی سبب شده حجم موجودیتها (مواد اولیه‘ کالای در جریان ساخت‘ و کالای ساخته شده) به میزان زیادی کاهش یابد و متعاقب با این امر هزینه های تولید نیز به نحو قابل ملاحظه ای کاهش یابد. هدف از این مقاله بررسی تأثیر اجرای سیستم JIT روی برخی از ابعاد حاسبداری مدیریت نظیر: مدیریت موجودی‘ برنامه ریزی‘ تصمیم گ...

Just in Time Hashing

In the past few years billions of user passwords have been exposed to the threat of offline cracking attempts. Such brute-force cracking attempts are increasingly dangerous as password cracking hardware continues to improve and as users continue to select low entropy passwords. Key-stretching techniques such as hash iteration and memory hard functions can help to mitigate the risk, but increase...

Just-In-Case Scheduling

This paper presents an algorithm, called JustIn-Case Schedulkg, for building robust schedules that tend not to break. The algorithm implements the common sense idea of being prepared for likely errors, just in case they should occur. The Just-In-Case algorithm analyzes a given nominal schedule, determines the most likely break, and reinvokes a scheduler to generate a contingent schedule to cove...
