Realtime Telemetry Processing System (RTPS) III: A Preview of Software Development in the 1990s

Hill, Jerry L. 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada / Software development is becoming less an art form and more an engineering discipline. Methods of software development which leave as little as possible to chance are constantly being sought and documented. However, the gap between what is written and what is actually applied is usually quite wide. The only way this gap can be narrowed is through practical application of these very detailed and complex methods. Since it is unlikely that the complexity of these methods will be reduced, automation must be employed wherever possible in the software development process. This paper addresses the successful development of software for the Navy's Realtime Telemetry Processing System III (RTPS III) using practical application of existing methodology in conjunction with a Computer Aided Software Engineering (CASE) tool. Based on this experience, the conclusion presents implications affecting software development the 1990s.

Standardiserad hantering av återanvändbara lastbärare : En fallstudie på Dynapac Compaction Equipment AB / Standardized management of reuseable load carries : A case study at Dynapac Compaction Equipment AB

Alderin Hedfelt, Frida, Tropp, Elin, Wickholm, Maja January 2024 (has links)
Bakgrund: Dynapac har använt återanvändbara lastbärare sedan 1980-talet, då de implementerade lastbärare för däck. Lastbärare används främst till att leverera gods och den centrala ståndpunkten är att det ska finnas en tillgänglighet på lastbärare för att kunna leverera godset i tid. Lastbärarna skickas sedan tillbaka till leverantören efter att godset har använts under hela produktionskedjan. Dynapac upplever stora problem när det gäller informationsflödet för deras återanvändbara lastbärare. Dynapac inte har något tillvägagångsätt att spåra dem, och de vet inte heller hur många lastbärare de äger eller vart de befinner sig.  Syfte: Syftet med studien är att utifrån Dynapacs hantering av återanvändbara lastbärare, föreslå en standardiserad rutin för de interna processer där lastbärare återfinns.  Metod: Studien baseras på en kvalitativ fallstudie på Dynapac Compaction Equipment AB, där data samlats in genom semi-strukturerade intervjuer och observationer. Urvalet för de semi-strukturerade intervjuerna baserades på ett målstyrt urval, där respondenterna specifikt valdes ut för att få fram representativ information till studien.  Resultat: Studien identifierade ett antal brister angående hanteringen av de återanvändbara lastbärarna. Bristerna har resulterat i faktumet att Dynapac är inkapabla att veta antalet lastbärare de äger eller hur många modeller som finns. Problemen som upptäcktes anses till stor del kunna standardiseras med hjälp av ett register över lastbärarna tillsammans med RFID-teknologi som kan integreras med Dynapacs affärssystem SAP. / Context: Dynapac have been using reusable load carriers since the 1980s, when they implemented carriers for tires. The load carriers are mainly used to deliver goods, and the central position is that there must be an availability of the load carriers to be able to deliver the goods on time. The load carriers are being shipped back to the supplier after the goods have been used in the assembly line. Dynapac is experiencing significant issues regarding the information flow of their reusable load carrier. They have no way of tracking or tracing the carriers, neither do they know how many carriers they own nor where they are.  Purpose: The purpose of the study is to propose a standardized routine for the internal processes involving load carriers, based on Dynapacs current processes for handling reuseable load carriers.   Method: The study constitutes a qualitative case study at Dynapac Compaction Equipment AB, where data has been collected through semi-structured interviews and observations. The selection for the interviews was based on targeted selection in order to obtain representative information for the final results of the study.  Results: The study identified several different deficiencies regarding the management of reuseable load carriers. The problems that were discovered can be standardized with the help of a register or index combined with RFID-technology that can be integrated with Dynapacs business system SAP. With the implementation of a register, can Dynapac also introduce continuous inventory to keep the problem from appearing again.
