1 Kuliah Sistem Pakar Pertemuan X Tahap III, IV Prototyping dan Pengembangan Sistem

2 Phase III Rapid Prototyping and Demonstration Prototype  Prototyping,  Prototyping, suatu proses untuk menghasilkan suatu prototipe  Prototype,  Prototype, ide bagi pembuat maupun pengguna (potensial) tentang cara suatu sistem akan berfungsi dalam bentuk lengkap dan bagaimana sistem nantinya akan dikembangkan maupun diperbaiki

3 Rapid Prototyping and a Demonstration Prototype  Build a small prototype  Test, improve, expand  Demonstrate and analyze feasibility  Complete design

4 Rapid Prototyping   Crucial to ES development   Small-scale system   Includes knowledge representation   Small number of rules   For proof of concept

5 Rapid Prototyping Process Refinement dari Pengembangan Sistem Rancangan Prototype Akuisisi Pengetahuan dan Representasi Testing, Studi Kasus Evaluasi, Pakar, Sumbang Saran Pengguna Analisis Hasil Perlu Perbaikan ? Start Akhir Prototyping YaYa Tidak

6 Prototyping: ES Development Life Cycle (PADI) Planning Analysis Design Implementation Prototype

7 Keuntungan dan Daya Tarik Prototipe  Keuntungan   Memperoleh gambaran Sistem   Memperoleh gambaran Perbaikan/Perawatan   Memperoleh gambaran ide, Hardware, Software serta Network (optional)   Memperkenalkan dan menjual Sistem pada calon “user” yang skeptis.   Mendemonstrasikan Sistem (sederhana)

8  Daya Tarik   Terjadi komunikasi yang baik antara sistem “perancang” dengan user   Perancang dapat bekerja lebih baik dalam menentukan kebutuhan user   User berperan lebih aktif dalam pengembangan sistem   Aplikasi sistem lebih mudah karena keterlibatan user secara aktif, sehingga user mengetahui apa yang diharapkan. Keuntungan dan Daya Tarik (lanjutan)

9 Phase IV Pengembangan Sistem   Develop the knowledge base   Define the potential solutions   Define the input facts   Develop an outline   Draw a decision tree   Create a knowledge map   Create the knowledge base   Test, evaluate, and improve (knowledge base)   Plan for integration

10 Development and Maintenance of Expert Systems Problem Identification and Feasibility Analysis – –The problem must be suitable for an expert to solve it. – –Find an expert for the project – –Cost effectiveness must be established 2. System Design and Expert System Technology Identification – –The system is designed with integration other subsytems and databases – –Domain knowledge – –Knowledge and inferencing is established with simple cases 3. Development of Prototype – –Knowledge Engineer works with the expert – –Specific Tool is chosen for the project

11 Development and Maintenance of Expert Systems (Continued) 4. Testing and Refinement of Prototype –Test with simple cases –Deficiencies in performance are noted. –End users test the prototypes. 5. Complete and Field the Expert System –The interaction with the environment,, users, and other information systems is tested –Documented –User training 6. Maintain the System –The system is kept current by updating the knowledge base –Interfaces with other information systems are maintained

12 Development and Maintenance of Expert Systems (Continued) Testing and Refinement of Prototype – –Test with simple cases – –Deficiencies in performance are noted. – –End users test the prototypes. 5. Complete and Field the Expert System – –The interaction with the environment, users, and other information systems is tested – –Documented – –User training 6. Maintain the System – –The system is kept current by updating the KB – –Interfaces with other information systems are maintained

13 Development & Maintenance of ESs Problem Identification and Feasibility Analysis System Design and ES Technology Identification Development of Prototype Testing and Refinement of Prototype Is the Performance Satisfactory? Complete and Field the ES Maintain ES No Yes ES Ready for Use

14 Development Team ES Software

15 Roles in Expert System Development   Expert – –Knowledge   Knowledge Engineer – –Knowledge acquisition tactics include interviews, protocol analysis, observation, and analysis of cases – –Must select a tool with the application of the knowledge acquisition facility   User – –End user with a simple shell – –Prototypes are used

16 Persyaratan Sistem Pakar yang Baik (Pertemuan 10/06 -)   Dikembangkan untuk menjawab kebutuhan   Kecepatan pemrosesan tinggi   Menambah kepakaran “user”   Mudah diperbaiki   Dapat menjawab pertanyaan sederhana   Dapat bertanya untuk mendapat info tambahan   Mudah diubah   Pengguna harus merasa menguasai SP   Tidak sulit bagi pengguna pemula   Kebutuhan input harus jelas dan sederhana

17 Sampai Jumpa di Pertemuan XI Selamat Belajar, Semoga Sukses
