Introduction Idea’s Origin y l t s o y C c n a d n u d e R 5/41

Introduction Existing Systems O A system is installed on server O Application runs on Ipad/Tablet (Client) thought server i. MENU O Bach Hop Company (BICWeb. VN) O Choosing dishes thought IPAD, tablet http: //www. bicweb. vn

Introduction Existing Systems ez. Menu http: //vienphuc. com/ezmproduct. htm

Introduction Idea’s Evaluating O Actual needs: - Lost time for waiting to note orders. - Have errors and lead to debate later when notes by papers. - High expense and hard to control a lots waiter. O None of the existing system is widely applied in Viet Nam because: - Price, - Functionality, - Usability, etc. The market is still available for our product. 8/41

Introduction Scope O Provide the basic functions: - Ordering: Provide a new electric device replace a traditional ways in ordering dishes. - Management: Provide a window management software to manage orders, billing, statistic and automatically distribute dishes to chef. O Research & apply formal methods development (Yakindu) into executable embedded system. O Provide a long-term stable system. O Have acceptable price. 9/41

Product Overview Introduction (cont) SMR SMO LCD Display RF module Radio signal ig na l Microprocessor USB module Ra di os Keypad RF module SMC Bus RF module Keypad Microprocessor 11/41

Introduction Priciple 12/41

Introduction Feature O Using SMO to select menu. O Support two languages: English or Vietnam O View dishes' status: not done, doing or done. O May cancel dishes if it haven’t been done yet. O Call waiter for additional or unusual request. O Automatic distribute orders to kitchen. O Quick billing. O Develop using “Yakindu” for easy maintain and update. 13/41

Introduction Risk O Half of project team members do not have experiences O O working in real project. The team leader lack of project management skill, experiences. None of the project team members has been work as tester position. The facilitation for developing the project maybe the risk (like places, equipment , etc…) Lack of experiences of estimating time and budget for developing project. 14/41

Yakindu Introduction YAKINDU O built on Eclipse is an open-source-toolkit O open source for the model-driven O available at Eclipse Labs development http: //statecharts. org of embedded systems 26/41

Yakindu Statechart Tools (SCT) 27/41

Yakindu Statechart Tools (SCT) Formalism similar to state machines as defined by David Harel, but: O self-contained with a well defined interface O with a cycle-based execution semantics v allows processing concurrent events v event-driven behavior can be defined on top v time control is delegated to the environment 28/41

Conclusion Testing (cont) O Embedded System Testing O RS 232 testing O Atmega 128 A testing O n. RFL 2401 testing O LCD display testing O Keyboard testing O Data transferring testing O Information System Testing O GUI testing O Functions testing O Insert database testing O Connect COM port testing 38/41

Conclusion Limitation O Control software design is monotonous O Software didn’t have many functions O Do not display all system operations O Database design is not in standard O Sometimes not operate reliability O Source code is quite complicated O Counter printed board O Operate in 9 V power only O Still cannot transfer data in a long distance (desire possible) O Design is not complete O Connection sometimes not reliability 39/41

Conclusion Future Improvement O Large restaurant O Expensive price O Provide software in tablet O Have all basic function O Can custom comment dishes O No need paper menu 40/41
