Based on CAD graph-driven technology, a kind of novel open architecture CNC system is put forward and designed together with the key hardware "PC+PMAC controller". The intelligent CNC system software including several function modules is developed under Visual C++6.0 environment. Graphic feature identification and geometric parameter extraction from CAD-part-drawing saved as DXF format are performed to control the relative motion between cutting tool and part. The ant-colony algorithm is applied to auto-optimize the cutting tool paths in machining process. The experiment results of a plane engraving machining example show that the proposed method is feasible, and the entire machining process no longer needs NC programming. The efficiency of CNC machining is improved greatly, and the true intelligent CNC machining can be realized when the advanced programming technologies are integrated in one system according to the proposed conception.

In this paper a socio-cognitive ACO-type algorithm is proposed for multi-criteria TSP problem optimization. This algorithm is rooted in psychological inspirations and follows other socio-cognitive swarm intelligence methods proposed up to now. This paper presents the idea and shows the applicability of the proposed algorithm based on selected benchmark functions from the scope of well-known TSPLIB library.

City express delivery demand is characterized by large quantities, small parcel sizes, dense batch frequency, and timeliness. To meet demand and control costs and CO2 emissions from parcel delivery, a collaborative delivery mode using bus vehicles and a truck fleet is proposed. A model is built to optimize delivery schemes based on a bus-road mixed network and thus minimize the fixed cost, the delivery cost, the compensation cost for the emitted CO2, and the unpunctuality penalty cost. An ant-colony algorithm is designed to solve the model. Delivery schemes for the 97 demand sites in a Chinese city are calculated under collaborative mode and truck-only mode. The advantages of a collaborative mode are verified by comparing the two types of delivery schemes.

Rotor machining is a traditional discrete manufacturing process, among which large amount of non-essential energy is being wasted. The machining process belongs to pipeline production, so a flow-shop scheduling model is built to optimize it. But when there are over three machines, this will be an NP-hard problem. We introduce an improved ant-colony algorithm to find the best solution and then use the real machining data to test it. The total energy consumption is reduced by over 10% and this shows the model and intelligent algorithm work well.

This paper studies how to exploit spatial data correlations to group sensor nodes into clusters of high data aggregation efficiency. The approach proposed in this paper first selects a set of cluster heads that form a dominating set. Then a set of nodes selected by ant-colony algorithm are added to the above dominating set to make all the nodes in the set connected. Simulation results demonstrate the effectiveness and efficiency of the designed approach.

To control the cost and optimize the resource utilization of enterprises, production layout problem draws recently more and more attention by industries;however, a study on this problem indicates there is a lack of research on production line design, which is a major issue in the layout problem. Traditional methodology mainly depends on the designer's experience and calls for theory analysis and quantitative study. This paper concerns the development of a multi-stage integer programming model to describe the production line layout problem, and employs a heuristic and ant-colony algorithm to solve the problem. A practical example illustrates the effectiveness of the model.

A scenario of multiple targets which need to be assigned to different UCAVs from different military bases has been established. The maximum execution time, hard time window, timing constraints, Maximum execution number of tasks, Speed and voyage loss were taken into consideration in this tasks allocation problem. Through the uses of ant-colony algorithm based on MTSP (Multiple Traveling Salesman Problem), the optimization problem had been solved efficiently, which made it more practical. Simulation results show that the proposed method is able to provide a reasonable project in a short time.
