High-level efficiency and safety are of great significance for improving the fighting capability of an aircraft carrier. One way to enhance efficiency and safety level is to organize the carrier aircraft into combat effectively. This paper studies the mission planning problem for a team of carrier aircraft launching, and a novel distributed mission planning architecture is proposed. The architecture is hierarchical and is comprised of four levels, namely, the input level, the coordination level,the path planning level and the execution level. Realistic constraints in each level of the distributed architecture, such as the vortex flow effect, the crowd effect and the motion of aircraft, are considered in the model. To solve this problem, a distributed path planning algorithm based on the asynchronous planning strategy is developed. The proposed Mission Planning Approach for Carrier Aircraft Launching(MPACAL) is validated using the setups of the Nimitz-class aircraft carrier.Compared to the isolated planning architecture and the centralized planning architecture, the proposed distributed planning architecture has advantages in coordinating the launch tasks not only belonging to the same catapult but also when all different catapults are considered. The proposed MPACAL provides a modeling method for the flight deck operation on aircraft carrier. 展开更多

Since the founding of new China in 1949, rural development in China has experienced three periods, which have been first the collective economy, second the household contract responsibility system, and third the chronological coordination of the urban and rural. Meanwhile, there are three types of statutory planning that guide rural construction and management in China, i.e., land use planning, land consolidation planning, and village and town planning. This paper summarizes their different characteristics in the three periods respectively. Firstly, the period of the collective economy from 1949 to 1978 is the embryonic stage of rural planning, during which land use planning was just introduced from abroad, while land consolidation planning and village and town planning had not yet been formed. In this period, rural planning had a strong planned economy feature. The following period of the household contract responsibility system from 1978 to 2003 is the growth stage of rural planning, during which all three types of planning developed their independent preparation, regulation, and management systems. In the period of urban and rural coordination from 2003 to the present, there has been a trend towards urban and rural integration and joint development among three types of planning. Based on the rural development history in China since 1949, this paper concludes that the three types of statutory planning have transformed in adapting to China’s national conditions toward a more standardized, legislated, and integrated mode. 展开更多

Motion planning is one of the most significant technologies for autonomous driving. To make motion planning models able to learn from the environment and to deal with emergency situations, a new motion planning framework called as'parallel planning' is proposed in this paper. In order to generate sufficient and various training samples, artificial traffic scenes are firstly constructed based on the knowledge from the reality.A deep planning model which combines a convolutional neural network(CNN) with the Long Short-Term Memory module(LSTM) is developed to make planning decisions in an end-toend mode. This model can learn from both real and artificial traffic scenes and imitate the driving style of human drivers.Moreover, a parallel deep reinforcement learning approach is also presented to improve the robustness of planning model and reduce the error rate. To handle emergency situations, a hybrid generative model including a variational auto-encoder(VAE) and a generative adversarial network(GAN) is utilized to learn from virtual emergencies generated in artificial traffic scenes. While an autonomous vehicle is moving, the hybrid generative model generates multiple video clips in parallel, which correspond to different potential emergency scenarios. Simultaneously, the deep planning model makes planning decisions for both virtual and current real scenes. The final planning decision is determined by analysis of real observations. Leveraging the parallel planning approach, the planner is able to make rational decisions without heavy calculation burden when an emergency occurs. 展开更多

Robots need task planning algorithms to sequence actions toward accomplishing goals that are impossible through individual actions. Off-the-shelf task planners can be used by intelligent robotics practitioners to solve a variety of planning problems. However, many different planners exist, each with different strengths and weaknesses,and there are no general rules for which planner would be best to apply to a given problem. In this study, we empirically compare the performance of state-of-the-art planners that use either the planning domain description language(PDDL) or answer set programming(ASP) as the underlying action language. PDDL is designed for task planning, and PDDL-based planners are widely used for a variety of planning problems. ASP is designed for knowledge-intensive reasoning, but can also be used to solve task planning problems. Given domain encodings that are as similar as possible, we find that PDDL-based planners perform better on problems with longer solutions,and ASP-based planners are better on tasks with a large number of objects or tasks in which complex reasoning is required to reason about action preconditions and effects. The resulting analysis can inform selection among general-purpose planning systems for particular robot task planning domains. 展开更多

Background: Many forested landscapes throughout the world involve a mix of public forest ownerships. This study explores how coordinated planning between two large public ownerships in Minnesota impact landscape-level trade-offs between timber production and production of core area of older forest (COF) for the region. COF is an important metric for wildlife habitat. Emphasis is on better understanding potential gains from both coordinated planning at the site-level where ownerships share stand boundaries and from coordinated planning at a broader policy level involving assumed values of COF by the public. The study area involves over 300,000 ha, 150,000 analysis units and a 100-year planning horizon. Methods: The concept of influence zones in modeling spatial interdependencies is described and implemented. The estimated total area of COF is assumed an important landscape metric for forest wildlife habitat condition for each forest planning period. COF has a surrounding buffer protecting it from edge effects. Differences are recognized between COF condition requirements and condition requirements for its surrounding buffer. A spatially-explicit harvest scheduling model is applied in conjunction with moving-windows techniques of GIS to find near-optimal management schedules for the large landscape. Multiple model runs are examined to help better understand both potential gains from coordinated planning and the tradeoffs between timber and COF production. Results: Results demonstrate the ability to incorporate detailed site-level COF production into management scheduling models for broad, landscape-level planning. For the study area and the assumed COF definitions, substantially larger gains are possible by coordinating COF value assumptions across ownerships, as compared to possible gains from coordinating on-the-ground management activities in areas involving shared stand boundaries. Although a general map of the study area shows a definite intertwining mosaic of ownership by the two large public agencies, a deta 展开更多

This paper constructs a dynamic conflict model that considers Decision Makers'(DMs)evolutional attitude using the option prioritization.The proposed evolutional attitude approach is based on the framework of the Graph Model for Conflict Resolution(GMCR).Compared with the existing state-based preference,the option prioritization is a more convenient and efficient approach to analyze larger models with consideration of the evolutional attitude,which exists broadly in the evolutional conflicts in reallife.This study reveals how the evolutional attitude of a DM succeeds in the overall evolution of conflict.The analysis unfolds that DMs change their attitude(s)consequent upon the changes in DMs and options available to them as conflict evolves from one level to the next.The changes in attitude of DMs during dynamic conflict situation have substantial effects on the equilibrium outcomes of a conflict.The proposed evaluation attitude-based approach is employed to analyze the conflict between the Punjab Government(G)and Heritage Campaigner and the Public(P)in Pakistan that appeared due to the inappropriate design,planning,and construction of an urban transport system project in Lahore,Pakistan.The present study demonstrates the modeling procedure of a two-level evolutional attitude-based conflict analysis.The results of the stability analysis reveal that improper(negative)attitude may result in undesirable and unexpected consequences,such as project temporalities and delays.This research provides a foundation for future research in urban project planning that employs strategic ways to avoid disputes caused by DMs'attitudes. 展开更多

Facing the new era of construction of socialism with Chinese characteristics, it is critical for the northeastern region of China to hold this new chance for its overall revitalization.The foundation and key of this revitalization lie in finding out problems in the urban development and then putting forward feasible countermeasures.This paper studies 34 prefecture-level cities in northeast China, and uses the coordination index to analyze the relationship between land and population, economy, and investment, of different types of cities in the region from 2000 – 2014, in order to discover problems in its urban development and provide planning countermeasures.Data shows that in northeast China, the imbalance between urban land expansion and population is significant, the imbalance between urban land use and either economic development or capital investment is periodical, for which the primary reasons include strong centralization effect of center cities, limited input on land resources, and weak industrial competitiveness.Correspondingly, the paper proposes planning strategies in terms of vitalizing stock land, enriching land use functions, and coordinating industrial resources, with an expectation of providing both the theoretical foundation for the economic revival in the northeastern region and a guidance on practice of revitalization strategies in all cities of the region. 展开更多
