When you stop looking for yourself, you will find the entire universe because what you are looking for is also looking for you. Anything you do persevere every day can open a door to the depths of your spirit. In silence, I slipped into the secret realm, and I enjoyed everything to observe the magic around me, and didn't make any noise. Why do you like to crawl when you are born with wings? The soul has its own ears and can hear things that the mind cannot understand. Seek inward for the answer to everything, everything in the universe is in you. Lovers do not end up meeting somewhere, and there is no parting in this world. A wound is where light enters your heart.
Chronic heart failure is not just a problem of the speed of heart rate! It is caused by the decrease in myocardial contraction and diastolic function, which leads to insufficient cardiac output, which in turn causes congestion in the pulmonary circulation and congestion in the systemic circulation. From causes, inducement to compensation mechanisms, the pathophysiological processes of heart failure are complex and diverse. By controlling edema, reducing the heart's front and afterload, improving cardiac comfort function, and preventing and treating basic causes, we can effectively respond to this challenge. Only by understanding the mechanisms and clinical manifestations of heart failure and mastering prevention and treatment strategies can we better protect heart health.
Ischemia-reperfusion injury is a phenomenon that cellular function and metabolic disorders and structural damage will worsen after organs or tissues restore blood supply. Its main mechanisms include increased free radical generation, calcium overload, and the role of microvascular and leukocytes. The heart and brain are common damaged organs, manifested as changes in myocardial metabolism and ultrastructural changes, decreased cardiac function, etc. Prevention and control measures include removing free radicals, reducing calcium overload, improving metabolism and controlling reperfusion conditions, such as low sodium, low temperature, low pressure, etc. Understanding these mechanisms can help develop effective treatment options and alleviate ischemic injury.

inventory decisions
Inventory cost and basic inventory model
inventory cost
Procurement cost
Refers to the cost consisting of the cost of purchasing inventory and transportation expenses
Ordering cost
fixed ordering cost
Costs that are relatively stable in each period to maintain a certain purchasing capacity
variable ordering cost
Costs that vary in direct proportion to the number of orders
storage cost
Fixed storage costs
Costs where the total amount is stable and has nothing to do with the quantity of inventory stored and the length of storage time
variable storage costs
The total amount depends on the quantity of inventory stored and the cost of storage time
stockout cost
It refers to the losses caused to the enterprise because the inventory quantity cannot meet the needs of production and sales in time.
economic order quantity
Calculation of inventory costs
Extended application of basic inventory model
One-time ordering, in-and-out decision-making
Decisions when there are quantity discounts
Decisions when order batch size is limited
Decisions when storage capacity is limited
Inventory decisions under uncertainty
Safety stock and inventory depletion costs
(1) Storage cost of safety stock quantity Since the beginning safety stock balance is equal to the ending safety stock balance, the unit storage cost of safety stock The unit storage cost of operating inventory is the same. Therefore, the storage cost of safety stock quantity is equal to the safety stock quantity. Multiply the unit storage cost of the inventory. The sum of depletion costs is minimized.
(2) Inventory depletion cost. Usually refers to the cost of alternative supply sources, the cost of customer or business reputation, the cost of stopping production during the inventory depletion period, etc. As an annual expected value, the inventory depletion cost is equal to the inventory depletion cost of a certain item multiplied by the number of orders scheduled per year multiplied by the probability of inventory depletion for an order. The purpose of safety stock decision-making is to determine how much insurance reserve is needed to reduce storage costs and inventory levels.
How to determine safety stock quantity
empirical method
The upper limit of safety stock = maximum delivery time * maximum daily consumption - normal number of days in the exchange period * average daily consumption
discontinuous probability method
Calculate the sum of the expected inventory depletion cost of different safety stock amounts and the storage cost corresponding to the safety stock amount, and then select the safety stock amount with the lowest total cost
Determination of reorder point
Reorder point = (number of days between purchases * average daily consumption) safety stock
Inventory turnover control
inventory turnover period
Procurement cycle control
Production cycle control
According to market supply and demand conditions, pull production or push production is adopted
Reduce activities that do not add value and shorten production cycles
Sales cycle control
