requirements management throughout the project cycle, for easy reading, I have my own harvest and views in accordance with the project stage to explore.Demand Research Phase :How to do demand research? How to communicate with customers?The problem seems very simple. If I ask some of my colleagues who have done demand research with customers, I think most of them will answer: talk to the customer about what they want, then let the designer do a axure, and finally take (and possibly the

First, the system hardware interface definitionThe hardware interface of the system is divided into the floor hardware interface, the elevator movement interface and the power part interface;1.1 Floor Hardware interfaceEach floor of the elevator has two buttons "upstream" and "downlink", there are two led digital tube respectively shows the two elevators on the floor, the digital tube has an arrow LED light

. 5. Describe how to use a good design method: 　　　　1. Information Hiding:Information Hiding is the foundation of structured design and object-oriented design. The concepts of functions and object-oriented encapsulation in the structure are derived from information hiding. The software industry has recognized this principle for the past decade.The following lists some information hiding principles.(1) layer and layer are added to the interface layer;(2) All classes and classes are accessed throug

switching ". because we often use if elseif else for status switching, if the status is determined to appear repeatedly, we need to think about whether the State mode can be used. it is suitable for internal states that are constantly changing. (2) A State includes two parts: the object + the attributes inside the object (attribute interface + specific attributes) An object must have its attributes, as well as its setter and getter. set its initial state and call the display state method (w

Believe the things that you have a right to believe (believe that you have the right to trust something )! This is the risk management ). We often say that the phrase "reluctant to give up a child without a wolf" is a risk in the field of software development, "Wolf" is the benefit. Risks and Opportunities always coexist, face risks, and dance a waltz with the bear with our bravery, wit, courage, and foresight, even with a few claw marks, it is our glorious mark. "If there is no risk on your nex

Floor Hardware interfaceEach floor of the elevator has two buttons "upstream" and "downstream" (the first layer and the seventh layer respectively only "upstream" and "downlink"), two led digital tube respectively shows about two elevators located on the floor, Arrow LED lights indicate the elevator running state (up, down, stop). The two buttons are electri

the current State are incomplete, because they do not have routing and custom error page handlers. This is the topic of the next section. 3.2. Implement application functions in the blueprint The transformation of the application factory leads to the complexity of routing. In a single script application, the application instance is global, so it is easy to use the app. route modifier to define routes. But now the application is created at runtime, an

In this elevator operation, I constructed an elevator request queue thread, a scheduler thread, three elevator threads, a file output thread, and a main thread

We spent 2 weeks on the elevator simulation program, I am very grateful to my partner Wang Chang classmate (blog address: http://www.cnblogs.com/naturewang/), in the process he gave mea lot of help, no there's his Help and I think we're not It's easy to get this program finished. Wang Chang classmate very careful, also very patient, in the process of writing a number of problems, he can be patient with me to solve, and also can carefully improve the p

Original question: A skyscraper have no more than floors, numbered from 0 to 99. It has n (1≤n≤5) elevators which travel up and down at (possibly) different speeds. For each i in {1, 2, ... n}, elevator number I takes T I (1≤t i≤100) seconds to travel between any and adjacent floors ( Going up or down).Elevators don't necessarily stop at every floor. What's worse, not every floor is necessarily accessible by an elevator.You is on the floor 0 and would

I. Multi-threaded KNOWLEDGE summary1. Thread SynchronizationThe knowledge about creating threads is not too much to describe. Let's start with the main story and talk about thread synchronization. As with the process synchronization in the operating system, the thread also faces the problem of resource sharing, and how to handle the resource sharing of threads is the most important place to use multithreading. In Java is the introduction of the concept of locking to deal with the relationship be

is to describe a simple elevator model. One person can draw very complex and detailed class digoal and sequence digoal, the other has a poor grasp of digoal details, but on the other hand, the latter considers that the top and bottom layers of the elevator are different from the middle layers and cannot be described in the same class, who should I hire? It is certainly not a UML diagram that can be very be

pages here return app The factory function returns the instance of the application created, but note that applications created using the factory function in the current state are incomplete because they do not have a Routing and custom error page handler.
