5 Overvejelser Omfang software bibliotek S95 level 3 MES 2 SCADA 1 PLC Applikationsafhængig Basic System Modules Equipment Modules Units Høj Lav Genbrugsgrad Behov for projekttilpasninger Lav Høj

6 Overvejelser Omfang software bibliotek S95 level 3 MES 2 SCADA 1 PLC Basic System Modules Equipment Modules Units Platform

7 Overvejelser Udvikling af software bibliotek Softwarebiblioteks anvendelighed = Kvalitet af software + Kvalitet af tilhørende dokumentation Design dokumenter kan bruges som grundlag til flere platforme! Softwarebibliotek+ tilhørende dokumentation + diverse guidelines = Framework

8 Overvejelser Brug og vedligeholdelse af software bibliotek Videreudvikling af softwarebibliotek - Produkt eller projektdrevet eller kombination? Distribution af opdateringer/opgraderinger af bibliotek Produkt eller projektdrevet?

9 Kundecase - Udvikling af software bibliotek Framework / Software Library Milk Pretreatment Cheese Plant Cheese Handl. Pre-storage & Packaging Storage Cheese, Fats & Oils Whey & Powder Packaging Powder Storage Powder Fats & Oils Plant Packaging Fats & Oils Chemicals & CIP Plants Utilities Building

10 Kunde case - Overvejelser Udvikling af software bibliotek Level/Range/Scope - framework Low Only basic elements High Complete system with all elements Resources required Low Mainly at initial phase High During all project phases Risk Unclear supply boundaries / responsibility Plant maintenance cost Cost - training of operators / technical staff Low Uncomplicated interface High Different solutions at various parts of the plant High Different solutions at various parts of the plant High Complicated interface Low Uniform solution throughout the plant Low Uniform solution throughout the plant

15 Kunde case Omfang af software bibliotek (framework)

16 Udgangsreplik! Fokusområder ifm. opbygning og brug af standard software bibliotek: Overvej omfang Hvor er der mest genbrug /effekt Er der ressourcer til at supportere det valgte omfang Brug internationale standarder som grundlag Dokumentation er grundlag for at softwarebibliotek bliver anvendt Inkluder diverse guidelines (Navngivning / struktur etc.) Overvej hvordan opdateringer skal distribueres Husk balance mellem At holde fast i udviklet standard / Være åben for nye muligheder & kundekrav (At være robust - ikke stivnet!)
