python 工厂流水线工件处理模拟

以下是一个简单的 Python 工厂流水线工件处理模拟示例，其中使用了类和方法来模拟工厂流程：

class Workpiece:
    def __init__(self, name, size):
        self.name = name
        self.size = size

class Conveyor:
    def __init__(self):
        self.workpieces = []

    def add_workpiece(self, workpiece):
        self.workpieces.append(workpiece)

    def remove_workpiece(self):
        if len(self.workpieces) > 0:
            return self.workpieces.pop(0)
        else:
            return None

class Machine:
    def __init__(self, name, size_limit):
        self.name = name
        self.size_limit = size_limit
        self.current_workpiece = None

    def load_workpiece(self, workpiece):
        if workpiece.size <= self.size_limit:
            self.current_workpiece = workpiece
            return True
        else:
            return False

    def process_workpiece(self):
        if self.current_workpiece is not None:
            self.current_workpiece.size -= 1
            if self.current_workpiece.size == 0:
                workpiece = self.current_workpiece
                self.current_workpiece = None
                return workpiece
        return None

conveyor = Conveyor()
conveyor.add_workpiece(Workpiece("A", 5))
conveyor.add_workpiece(Workpiece("B", 3))
conveyor.add_workpiece(Workpiece("C", 7))

machine1 = Machine("Machine 1", 4)
machine2 = Machine("Machine 2", 6)

while True:
    # Load workpiece onto machine 1
    if machine1.current_workpiece is None:
        workpiece = conveyor.remove_workpiece()
        if workpiece is not None:
            if machine1.load_workpiece(workpiece):
                print(f"Loaded {workpiece.name} onto {machine1.name}")
            else:
                print(f"{workpiece.name} is too big for {machine1.name}")

    # Process workpiece on machine 1
    if machine1.current_workpiece is not None:
        workpiece = machine1.process_workpiece()
        if workpiece is not None:
            print(f"Processed {workpiece.name} on {machine1.name}")
            conveyor.add_workpiece(workpiece)

    # Load workpiece onto machine 2
    if machine2.current_workpiece is None:
        workpiece = conveyor.remove_workpiece()
        if workpiece is not None:
            if machine2.load_workpiece(workpiece):
                print(f"Loaded {workpiece.name} onto {machine2.name}")
            else:
                print(f"{workpiece.name} is too big for {machine2.name}")

    # Process workpiece on machine 2
    if machine2.current_workpiece is not None:
        workpiece = machine2.process_workpiece()
        if workpiece is not None:
            print(f"Processed {workpiece.name} on {machine2.name}")
            conveyor.add_workpiece(workpiece)

    # End simulation if conveyor is empty and machines are idle
    if len(conveyor.workpieces) == 0 and machine1.current_workpiece is None and machine2.current_workpiece is None:
        break

这个示例模拟了一个具有两个机器的工厂流水线，并处理了三个工件。每个工件都有一个名称和大小，大小用于确定可以在哪些机器上加工。每个机器都有一个名称和大小限制，超过大小限制的工件将无法加工。流水线包含一个传送带，可以添加和移除工件。在每个循环迭代中，程序将检查哪些机器是空闲的，并尝试将工件加载到它们的上面。然后，程序将处理每个机器上的当前工件，并将其移到下一个机器或传送带上。最后，当传送带为空且所有机器都空闲时，模拟将结束。
