発注点補充方式（ｂ）は、医薬品が消化されて、在庫量が発注点に達した時点で、次の納入日までの消化量を推定して、発注点から医薬品が補充されるまでの期間に消化される薬品量を推定して推定消化薬品量を求め、安全在庫量を考慮した適正在庫量までの薬品量を補充する方式である。その配送日の在庫量は、適正在庫量に安全在庫量を加算した在庫となる。この補充在庫量は、発注点補充量算出手段１１ｄで求められる。理論在庫量は、発注点での在庫量であり、推定消化薬品量は発注点配から送日までに消化される医薬品量である。次の配送日の医薬品は、数２で求められた補充数量の医薬品が配送される。
【００３３】
【数２】

【００３４】
定期補充方式（ｃ）は、予め設定した日付に設定数量を補充する方式である。医薬品の消化量が規則的である場合は、この方式で補充する。この補充方式では、医薬品の消化傾向が需要予測手段１７による統計手法によって解析することで、医薬品の消化が規則的であることが判定できる。ある医薬品の補充形態が、定期補充方式（ｃ）であれば、補充周期が医薬品の使用期間（有効期限）内であって、かつ医薬品の消化傾向を把握して統計的に求められる消化周期を越えないように配送計画を作成して、医薬品の補充周期が設定される。定期補充量算出手段１１ｅでは、所定周期で消化される医薬品の補充量が算出される。配送計画作成手段１８では、補充量に合わせて配送計画を作成する。
【００３５】
使用量補充方式（ｄ）は、送信された消化量をそのまま補充する。この方式は、基本的な補充形態であり、箱単位で補充する場合に適する。すなわち、使用量補充方式では、消化された医薬品量を箱単位でその都度納入する方式であり、配送計画から考慮すれば、効率的ではないが、消化薬剤の統計的なデータが得られるまでは、好ましい納入形態である。医薬品の消化傾向が把握できれば、徐々に（ａ）〜（ｃ）の方式へと移行することによって、効率的に配送計画が行える。
【００３６】
医薬品の消化傾向は、顧客別使用データ記憶装置１２に記憶された刻々の各顧客の各医薬品毎の消化薬品データから需要予測手段１７による統計手段によって把握される。なお、統計手段は、卸業務用コンピュータ１１による需要予測手段１７で処理され、日単位で消化される各顧客毎で各医薬品の消化傾向が把握されている。無論、需要予測手段１７は分散処理してもよい。
【００３７】
上記４つの補充形態は、需要予測手段１７によって、各顧客の各医薬品毎の統計手段を駆使して消化傾向を把握し、薬品補充形態選択手段１１で選択する。統計手段では、医薬品の消化傾向を把握するもので、時間の経過に合わせて一定傾向を示す「傾向変動」、ある周期に合わせて変化する「循環変動」、季節に合わせて変化する「季節変動」、突発的に変化が起きる「不規則変動」等に分類がなされる。さらに、突発的な変化の周期性が判断される。このように需要予測手段１７によって、消化傾向が解析された後、薬品補充形態選択手段１１では、補充方式が選択される。需要予測手段１７で予測された消化傾向はコード化され、顧客別在庫データ記憶装置１３の各医薬品に対応して、コード化された消化傾向が顧客別在庫データ記憶装置１３に記憶される。薬品補充形態選択手段１１では、例えば、「傾向変動」，「循環変動」と判定された医薬品は（ａ）自動補充方式が選択され、「循環変動」，「不規則変動」と判断された場合は（ｂ）発注点補充方式が選択される。「季節変動」と判定された医薬品は（ｄ）使用量補充方式が選択される。さらに、顧客の規模等の要因で、補充方式が選択される。
【００３８】
また、予め補充方式が設定できる場合は、（ａ）〜（ｄ）の何れかの方式を選択し、顧客別在庫データ記憶装置１３にその補充形態を記憶するようにする。さらにまた、先ず、使用量補充方式（ｄ）で消化薬剤を顧客に配送して、その消化傾向を把握して、（ａ）〜（ｃ）の補充形態に移行できる。また、顧客の要求により、何れかの方式に固定してもよいが、薬品補充形態選択手段により、医薬品の消化傾向から（ａ）〜（ｃ）の補充形態に移行するようにするのが在庫管理上望ましい。
【００３９】
次に、本発明の医薬品自動補充システムの動作について、図面を参照して説明する。顧客である調剤薬局又は医療機関で消化した医薬品の消化薬品データ等（「顧客コード」，「薬品コード」，「診療科コード」，「消化量」，「薬品名」等）がレセプトコンピュータ、バーコードシステム、オーダリングシステム又は電子カルテの何れかから抽出されて、所定のフォーマットで送信される。これらのデータは、ＷＷＷサーバ１９に毎日送信されて、顧客別使用データ記憶装置１２に時系列で入力され記憶される。顧客別使用データ記憶装置１２には、顧客毎の記憶領域が設けられ、顧客毎に消化薬品データ等が格納される。
【００４０】
卸業務用コンピュータ１１には、顧客別使用データ記憶装置１２に格納された消化薬品データを、各顧客の各医薬品が所定期間で消化した合計消化薬品量を算出する消化薬品量算出手段１１ｂを備えており、消化薬品量算出手段１１ｂで顧客別の各医薬品の消化薬品量を集計して、各顧客の各薬品コード毎に集計されて合計消化薬品量が算出される。顧客別在庫データ記憶装置１３には、各顧客の医薬品の在庫データが格納されている。
【００４１】
医薬品の補充数量（補充量）は、その医薬品の補充方式に応じて、自動補充量算出手段１１ｃ（数１の演算式）、または発注点補充量算出手段１１ｄ（数２の演算式）、または定期補充量算出手段１１ｅにより求められる。或いは、消化薬品量がそのまま顧客に補充される。この補充量の算出は、顧客別在庫データ記憶装置１３に格納された在庫データによる各医薬品の先の在庫量と、消化薬品量とによって、適正在庫量と安全在庫量等を考慮して、顧客毎の各医薬品の補充薬品量が算出される。
【００４２】
本実施形態の需要予測手段１７では、顧客毎に各医薬品の消化傾向が統計的に処理されて、各顧客毎に各医薬品の消化傾向（「傾向変動」、「循環変動」、「季節変動」、「不規則変動」等）が分析される。即ち、医薬品の消化傾向とは、「傾向変動」では医薬品の消化が一定傾向で払い出されるもの、「不規則変動」とは不定期に払い出されるもの、「循環変動」とは周期的に払い出されるもの、「不規則変動」とは、払い出し数量の変動が大きいもの、さらには、診療科に依存するもの、季節的要因により消化量の変動が大きいもの等が統計的に把握される。さらに、需要予測手段１７では、統計処理に基づいて、顧客毎に各医薬品の適正在庫量を推定することができる。
【００４３】
さらに、需要予測手段１７で推定さられた適正在庫量は、顧客別適正在庫データ記憶装置１５に記憶される。配送計画作成手段１８は、適正在庫量や需要予測手段１７で算出された顧客毎の各医薬品の消化傾向、消化量等に基づいて、基本的な配送日と補充量の割付が行われて配送計画が作成される。医薬品の補充量が求まれば、配送日に補充される医薬品の補充量が顧客別配送日データ記憶装置１６に各医薬品毎の配送計画に合わせて記憶され、この配送計画に基づいて、顧客に医薬品が配送される。
【００４４】
また、本発明の医薬品自動補充システムでは、各医薬品の在庫量が安全在庫量及び発注点在庫量を下回った場合、及び消化量の変動が多い場合、警告表示をＣＲＴやＬＣ表示装置に表示したり、警報を発したりして、報知する通報手段を備えている。各医薬品毎に顧客の医薬品の在庫が、例えば安全在庫を下回った時点で通報手段が作動させて警告することで、在庫切れによる緊急配送を解消することができる。各顧客の医薬品の在庫量を安全在庫量で監視することで、注意を喚起することができ、緊急納品回数を低減することができる。
【００４５】
【発明の効果】
上述のように、本発明によれば、医薬品卸業者が顧客の消化した医薬品の量を把握して、自動的に設定した補充量、又は在庫量が発注点に達した時点で、配送日までの消化量を推定して設定して補充量を求めて、顧客に医薬品を配送するようにした医薬品自動補充方法及びそのシステムであり、顧客側の医薬品の発注業務、及び在庫管理業務が極めて簡便なものとなる利点がある。一方、医薬品卸業者は、計画的な配送業務が可能であるとともに、在庫を切らした医薬品を緊急に配送する回数を低減することができる利点がある。
【００４６】
また、本発明によれば、インターネットを介してデータの送受信が可能であるので、顧客側のコンピュータシステムに設けられたＷＷＷブラウザの機能を利用して、顧客それぞれの在庫状況を確認することが可能である利点があり、顧客は薬品の在庫管理における無駄な投資を行う必要がない利点がある。
【００４７】
また、本発明によれば、各顧客の医薬品の在庫量が安全在庫を下回ったことを、医薬品卸業者が検知して、在庫が切れる旨の警告をすることで、在庫切れとなる前に医薬品を配送することが可能となり、緊急納品回数を低減することができる利点がある。

In this embodiment, the optimal medicine replenishment form is selected each time.
[0029]
  There are (a) automatic replenishment method, (b) order point replenishment method, (c) periodic replenishment method, and (d) usage amount replenishment method. Replenishment forms of each medicine are classified into the following four forms, and an optimal form is selected from these forms to replenish the medicine to the customer.
[0030]
  In the automatic replenishment method (a), the digestion data stored in the customer-specific use data storage device 12 is digested every predetermined period.amountThe total amount is calculated by the calculating means 11b, the amount of digestive chemicals is calculated, and the amount of digestive chemicals is calculated from the theoretical stock quantity by the digestive chemical amount replenishment amount calculating means. This is a method for determining. In calculating the replenishment quantity, the automatic replenishment quantity calculation means 11c performs the arithmetic processing shown in Equation 1 to calculate the replenishment quantity. In the delivery plan creation means 18, a delivery plan is created so as to deliver the digested medicine, that is, the supplemented quantity of medicine obtained in Equation 1.
[0031]
[Expression 1]

[0032]
  The reorder point replenishment method (b) is a period from when the drug is digested to when the inventory amount reaches the order point, the amount of digestion up to the next delivery date is estimated and the drug is replenished from the order point. This is a method for estimating the amount of chemicals that can be digested, obtaining the estimated amount of digested chemicals, and replenishing the amount of chemicals up to the appropriate stock amount considering the safety stock amount. The stock amount on the delivery date is a stock obtained by adding the safe stock amount to the appropriate stock amount. The replenishment inventory amount is obtained by the order point supplement amount calculation means 11d. The theoretical stock quantity is the stock quantity at the order point, and the estimated digestive medicine quantity is the amount of the pharmaceutical product that is digested from the order placement to the delivery date. For the next delivery date, find 2MeraThe replenished quantity of the drug is delivered.
[0033]
[Expression 2]

[0034]
  The periodic replenishment method (c) is a method of replenishing a set quantity on a preset date. If the amount of drug digestion is regular, it is replenished in this manner. In this replenishment method, it is possible to determine that the digestion of the medicine is regular by analyzing the digestion tendency of the medicine by a statistical method by the demand prediction means 17. If the replenishment form of a certain medicine is the periodic replenishment method (c), the replenishment cycle is within the use period (expiration date) of the medicine, and the digestion cycle that is statistically determined by grasping the digestion tendency of the medicine A delivery plan is created so as not to exceed, and a drug replenishment cycle is set. In the periodic replenishment amount calculating means 11e, the replenishment amount of the medicine that is digested in a predetermined cycle is calculated. The delivery plan creation means 18 creates a delivery plan according to the replenishment amount.

Statistical means is to grasp the digestion tendency of pharmaceuticals. “Trend fluctuation” that shows a constant trend over time, “Circular fluctuation” that changes with a certain period, “Season fluctuation that changes with the season” ”And“ irregular fluctuations ”in which changes occur suddenly. In addition, sudden changesofPeriodicity is determined.in this wayAfter the digestion tendency is analyzed by the demand prediction means 17, the medicine replenishment form selection means 11 selects the replenishment method.The digestion tendency predicted by the demand forecasting means 17 is coded, and the digestion tendency coded according to each medicine in the customer-specific inventory data storage device 13.ButIt is stored in the customer-specific inventory data storage device 13. In the medicine replenishment form selection means 11,For example, drugs that are judged as “trend fluctuation” or “circulation fluctuation”(A)Automatic replenishment methodChoiceIf it is judged as “circular fluctuation” or “irregular fluctuation”(B)Reorder point replenishment methodChoiceIs done. Drugs that are determined to be “seasonal”(D)Usage replenishment method isChoiceIs done. Furthermore, the replenishment method is selected depending on factors such as the size of the customer.
[0038]
  When a replenishment method can be set in advance, one of the methods (a) to (d) is selected, and the replenishment form is stored in the customer-specific inventory data storage device 13. Furthermore, first of all, the digestion drug is delivered to the customer by the use amount replenishment method (d), the digestion tendency is grasped, and the transition to the replenishment mode of (a) to (c) is made.it can. Also, depending on the customer's request, it may be fixed to either method,By chemical replenishment form selection means,It is desirable from the viewpoint of inventory management to shift to the replenishment forms (a) to (c) due to the tendency to digest pharmaceuticals.
[0039]
  Next, the automatic medicine replenishment of the present inventionSystem behaviorWill be described with reference to the drawings. Digestive drug data (“customer code”, “drug code”, “clinical code”, “digestion amount”, “drug name”, etc.) of the drug digested by the customer's dispensing pharmacy or medical institution) is received on the receipt computer, bar It is extracted from any one of the code system, the ordering system, and the electronic medical record, and transmitted in a predetermined format. These data are transmitted to the WWW server 19 every day, and are input and stored in the customer-specific usage data storage device 12 in time series. The use data storage device 12 for each customer is provided with a storage area for each customer, and digestive drug data and the like are stored for each customer.
[0040]
  The wholesale business computer 11 includes digestive drug amount calculation means 11b for calculating the total digestive drug amount that each drug of each customer has digested in a predetermined period from the digestive drug data stored in the customer-specific use data storage device 12. The digestive drug amount calculating means 11b totals the digestive drug amount of each drug for each customer, and the total digestion drug amount is calculated for each drug code of each customer. The customer-specific inventory data storage device 13 stores drug inventory data of each customer.
[0041]
  The replenishment quantity (replenishment amount) of the medicine is determined according to the replenishment method of the medicine, the automatic replenishment amount calculation means 11c (calculation formula of Formula 1), the order point replenishment quantity calculation means 11d (calculation formula of Formula 2) It is calculated | required by the periodical replenishment amount calculation means 11e. Or digestive chemical amountButIt is replenished to the customer as it is. This replenishment amount is calculated based on the inventory amount stored in the customer-specific inventory data storage device 13 according to the inventory amount of each medicine and the digestive drug amount, taking into account the appropriate inventory amount and the safety inventory amount. The amount of supplement for each drug is calculated.
[0042]
  In the demand prediction means 17 of this embodiment, the digestion tendency of each medicine is statistically processed for each customer, and the digestion tendency (“trend fluctuation”, “circulation fluctuation”, “seasonal fluctuation”) of each medicine for each customer. , “Irregular fluctuations”, etc.) are analyzed. In other words, the tendency of drug digestion is that “disease fluctuations” are paid out with a constant tendency of drug digestion, “irregular fluctuations” are paid out irregularly, and “circulation fluctuations” are paid out periodically What is “irregular fluctuation” is statistically grasped, for example, that there are large fluctuations in the amount paid out, furthermore, those that depend on the medical department, and those whose fluctuations in digestion are large due to seasonal factors. Furthermore, in the demand forecasting means 17, based on statistical processing, the appropriate inventory amount of each pharmaceutical for each customerEstimatecan do.
[0043]
  Furthermore, the demand forecasting means 17EstimatedThe appropriate stock amount thus obtained is stored in the proper stock data storage device 15 for each customer. The delivery plan creation means 18 performs distribution by assigning the basic delivery date and the replenishment amount based on the proper inventory amount and the digestion tendency and the digestion amount of each medicine calculated by the demand prediction means 17. A plan is created. When the replenishment amount of the medicine is obtained, the replenishment amount of the medicine to be replenished on the delivery date is stored in the customer-specific delivery date data storage device 16 according to the delivery plan for each medicine, and the customer is based on this delivery plan. Drugs are delivered.
[0044]
  In addition, the automatic medicine replenishment system of the present invention displays a warning display on the CRT or LC display device when the stock quantity of each medicine falls below the safety stock quantity and the order point stock quantity and when the digestion quantity varies greatly. Or a warning means for issuing a warning. For example, when the customer's medicine stock falls below the safety stock for each medicine, the notification means is activated to give a warning so that the emergency delivery due to the out of stock can be eliminated. By monitoring the stock amount of pharmaceuticals of each customer with the safety stock amount, attention can be drawn and the number of emergency deliveries can be reduced.
[0045]
