Abstract.
The proposed method can provide the useful information to manage total processes in civil engineering.
In the civil engineering industry, the aim of project control is to ensure that projects finish on time, within budget and achieve other project objectives.
Despite the wide use of these methods and software packages in practice, many civil engineering projects still suffer time and cost overruns.
This operation may belong to either essential or contributory processes. 5) Cleaning: an operation dedicated to remove rubbish and waste materials from workstations or from construction sites.

In this paper, the life-cycle of large-scale petroleum engineering project has been analyzed.
Drilling engineering has the characteristics of multidisciplinary, multi-disciplinary, multi-disciplinary, strong technology.
In order to improve management level of drilling engineering, the single-well drilling engineering project management has been implemented in China, in order to achieve with as less input with much output.
Furthermore, we conclude by discussing three key links.
The establishment of drilling engineering plan is based on the long-term plans and annual plans of drilling engineering, which is equivalent to the drilling project feasibility analysis process, as shown in Fig.7.

Abstract.
Its basic idea is: a probability model or random process needs to be constructed firstly to make its parameter equaling to the key to the question for the sake of pursuing solutions in math, physics, engineering technology and production management; then the statistical characteristic of the parameter is calculated through observing and sampling the model or process; finally the approximate value of solution is given, while the solution’s accuracy can be explained with standard variation of estimated value.

Micro-detonation of striking arc machining (MDSAM) is a new machining technology for engineering ceramics rough machining.
Introduction Due to their low density, superior wear resistance, and high temperature strength, engineering ceramic materials are increasingly being used for critical components in engineering systems [1].
Micro-detonation of striking arc machining (MDSAM) is a newly developed special rough machining technology for engineering ceramics [3].
Furthermore, the recoil melting materials splash to the nozzle surface and lead to the expansion of nozzle diameter.

High-quality agro-materials are organized directly from high-credit manufacturers to effectively decrease a lot of inferior agro-materials into market [1].
For decreasing cost of agro-materials, this linear barcode is adopted as ID tag.
Agro-materials logistics process Figure 2.
So every participant of agro-materials transaction must sign its data transmitted using his private key.
