算法描述

目前在物流，企业用工等领域，都有着大量的通过算法对接到的订单进行智能分配的需求。本文模拟的是用户下订单，然后商家接到订单，由配送人员进行派送的场景。在实际的应用中类似于百度外卖等有着非常多的实际应用。这种问题因为算法的复杂度太高，很难在短的时间周期内求解成功，所以有了像遗传算法，退火算法等启发式算法，以便在短的时间内能够求出近似的最优解。

本文模拟8个骑士，40个订单和40个商家进行计算。

算法描述

目前在物流，企业用工等领域，都有着大量的通过算法对接到的订单进行智能分配的需求。首先设计bean，商家接到订单的bean，这里需要商家和订单的坐标信息。

        this.orderx = orderx;

        return ordery;

    }

    public void setOrdery(String ordery) {

        this.ordery = ordery;

    }

 

}

模拟40个商家接到40个订单，其中商家和订单都可以是同一坐标位置，后续会考虑将坐标相近的位置进行聚类计算。
