NHS 家庭醫師預約系統的容量管理：從航空與電影院學到的啟示

 NHS 家庭醫師預約系統的容量管理：從航空與電影院學到的啟示

在許多產業中，企業必須管理一種特殊的資源：短效容量（Perishable Capacity）。例如飛機座位、飯店房間或電影票，一旦時間過去，未被使用的容量就永遠消失。

有趣的是，英國 NHS 的家庭醫師（GP）預約系統其實面臨非常類似的問題。

每天診所能提供的門診時段是固定的。如果病人沒有出席，這個時間就無法再利用，等於永久浪費。

然而，與航空或電影院不同的是：
GP 並不直接向病人收費。因此，像動態定價這樣的策略無法直接套用。但其中一些容量管理的原則仍然具有參考價值。

核心限制：GP 的門診時間

在多數基層醫療系統中，真正的限制通常是 醫師時間。

一間典型 GP 診所通常具有：

• 固定數量的醫師

• 固定長度的看診時間

• 每天固定的門診時段

這代表每天可提供的看診數量其實是有限的容量。

同時，對 GP 的需求往往高於可提供的門診數量。

隱藏的問題：未到診（No-show）

醫療預約系統的一大問題是 病人未到診。

病人可能因為：

• 忘記預約

• 症狀已經好轉

• 工作或個人因素無法前往

當這些情況發生時，該時段就變成未被使用的容量。

在 NHS 系統中，每年因為未到診而浪費的門診時段可能達到數百萬次。

超額預約是否可行？

航空公司面對相似的不確定性時，通常會採用 超額預訂（Overbooking）。

因為他們知道一定比例的乘客不會出現，所以會稍微多賣一些票。

類似概念其實也可以謹慎應用在醫療預約系統。

例如，如果歷史資料顯示 10% 病人會缺席，診所可以在某些時段稍微多安排一些預約。只要控制得當，就能減少浪費的門診時間。

不過，由於醫療服務涉及病人安全與品質，因此必須更加謹慎。

沒有價格，也能有「彈性分配」

雖然 NHS 不能使用價格調整需求，但仍然可以透過其他方式進行 彈性分配。

例如：

1. 依優先程度安排

門診可以分成不同類型：

• 當日緊急門診

• 一般預約門診

• 線上或電話諮詢

這能讓有限的 GP 時間優先給最需要的病人。

2. 分時段釋放預約

部分診所會：

• 保留當日門診給急性需求

• 提供提前預約給慢性或計畫性需求

這可以更好地配合病人的需求模式。

3. 數位分流（Digital Triage）

線上系統可以先評估病人的需求，並引導到：

• GP 醫師

• 護理師

• 藥師

• 自我照護建議

如此一來，GP 的時間就能用在最需要醫師專業判斷的病人身上。

核心概念：保護最稀缺的資源

在基層醫療中，最珍貴的資源其實是 醫師時間。

就像航空公司希望每一個座位都能創造價值，醫療系統也需要確保每一個門診時段都能真正幫助病人。

這並不是把醫療完全商業化，而是運用一些容量管理的思維：

• 減少未使用的門診時段

• 將有限資源分配給最需要的人

• 管理需求的不確定性

不同的目標

航空或娛樂產業的目標是 最大化利潤。

而在像 NHS 這樣的公共醫療系統中，真正的目標是：

在有限醫療資源下，最大化病人的可及性與健康結果。

即使沒有價格機制，更智慧的預約與需求管理仍然可以讓醫療系統更有效率地運作。

Flexible Capacity Management for NHS GP Appointments: Lessons from Airlines and Movie Theaters

 Flexible Capacity Management for NHS GP Appointments: Lessons from Airlines and Movie Theaters

Many industries face the challenge of managing perishable capacity—resources that lose all value if they are not used at a specific time. Airline seats, hotel rooms, and movie tickets are classic examples. Once the flight departs or the movie starts, any unused capacity is permanently lost.

Interestingly, a similar challenge exists in healthcare systems such as the UK NHS GP appointment system. Every day, GP clinics have a fixed number of appointment slots. When a patient fails to attend, that appointment time is permanently lost.

However, unlike airlines or cinemas, GPs do not charge patients directly for appointments, which means traditional price-based solutions cannot be used. Even so, some of the underlying principles of capacity management can still be applied.

The Core Constraint: GP Appointment Slots

In most primary care systems, the real constraint is doctor time.

A typical GP clinic might have:

• A limited number of doctors

• Fixed consultation lengths

• A fixed number of appointment slots per day

This creates a hard limit on how many patients can be seen.

At the same time, demand for GP services is often higher than the available capacity.

The Hidden Problem: No-Shows

A major challenge in healthcare scheduling is patient no-shows.

Patients may miss appointments because they:

• Forget the appointment

• Recover before the visit

• Cannot attend due to work or personal issues

When this happens, the appointment slot becomes unused capacity. Unlike other industries, this time cannot be recovered or reused.

In some NHS clinics, missed appointments represent millions of lost consultation slots every year.

Can Overbooking Work in Healthcare?

Airlines deal with similar uncertainty by using overbooking. They sell slightly more tickets than seats because they know a certain percentage of passengers will not show up.

A similar concept can be cautiously applied in healthcare scheduling.

For example, if historical data shows that 10% of patients miss appointments, clinics might schedule slightly more patients than the theoretical capacity. When done carefully, this can reduce wasted appointment slots while still keeping waiting times manageable.

However, healthcare requires much greater caution because patient care quality must remain the top priority.

Alternatives to Price-Based Flexible Pricing

Since NHS patients do not pay directly for GP visits, traditional dynamic pricing is not possible. However, systems can still introduce forms of flexible access.

Examples include:

1. Priority-based booking

Different appointment types can be prioritized:

• Urgent same-day appointments

• Routine appointments scheduled in advance

• Remote consultations for minor issues

This allows limited GP time to be allocated more efficiently.

2. Time-based release of appointments

Some clinics release appointments at different times:

• Same-day appointments for urgent needs

• Advance booking for planned care

This helps match appointment availability with patient demand patterns.

3. Digital triage systems

Online triage tools can assess patient needs and direct them to:

• GP consultations

• Nurse practitioners

• Pharmacists

• Self-care advice

This ensures GP time is used for patients who need it most.

The Core Principle: Protecting the Constraint

In operational terms, the most valuable resource in primary care is clinician time.

Just as airlines try to maximize the value of each seat, healthcare systems must ensure that every available consultation slot delivers meaningful patient care.

This does not mean treating healthcare like a commercial ticketing system. Instead, it means applying similar capacity management principles:

• Reduce unused capacity (missed appointments)

• Allocate limited resources to the highest-need patients

• Manage uncertainty in demand

A Different Objective

In industries like aviation or entertainment, the goal is maximizing profit.

In healthcare systems such as the NHS, the goal is different:

maximizing patient access and health outcomes with limited clinical capacity.

Even without direct pricing mechanisms, smarter scheduling and demand management can help healthcare systems make better use of their scarce resources.

彈性定價與超額預訂：最大化短效容量商品的獲利

 彈性定價與超額預訂：最大化短效容量商品的獲利

許多產業銷售的產品具有一個共同特性：保存期限非常短。例如飛機座位、電影票、飯店房間或演唱會座位，一旦時間過去，這些產品就完全失去價值。

飛機起飛後的空位、電影開場後未售出的座位，都無法留到之後再賣。

這類產品通常被稱為 「短效容量（Perishable Capacity）」。

從經營管理的角度來看，企業的目標不只是把所有座位賣完，而是要從有限的容量中創造最大的獲利。

真正的限制：固定容量

在航空公司、電影院、飯店或活動場館中，最主要的限制通常是 固定容量：

• 飛機只有固定數量的座位

• 電影院每一場只有固定座位

• 演唱會場地也有固定容納人數

由於短期內很難增加容量，企業面臨的核心問題是：

如何從每一個座位創造最高的收益？

這正是 彈性定價（Flexible Pricing） 與 超額預訂（Overbooking） 發揮作用的地方。

彈性定價：同一個座位，不同價格

不同顧客對同一個產品的價值感受並不相同。

以航空公司為例，乘客通常可以分成不同類型：

• 提早規劃、尋找便宜票價的旅客

• 對價格較敏感的休閒旅客

• 臨時出差、願意支付高價的商務旅客

電影產業也有類似情況：

• 平日白天看優惠場的觀眾

• 週末觀影的一般觀眾

• 首映或熱門電影願意付更高票價的影迷

如果企業只設定 單一票價，就可能錯失部分收益。

彈性定價透過時間、需求與顧客行為調整價格，例如：

• 提早購買的票價較低

• 接近時間或需求增加時價格提高

這樣可以在確保基本需求的同時，也能從願意支付較高價格的顧客身上獲得更多收益。

為什麼最佳策略可能會留下空位

直覺上，企業似乎應該把所有座位都賣完。

但如果每一場都很快售罄，通常代表票價設定太低，因為市場需求其實超過了供給。

最佳定價通常會讓需求 接近容量，但不一定完全相等。因此在某些情況下，可能會出現少數空位。

看似浪費，但其實可能代表價格已經接近市場願意支付的最佳水準。

超額預訂：應對不確定性

另一個常見問題是 未到場（No-show）。

• 乘客可能錯過航班

• 觀眾可能臨時取消看電影

• 飯店客人可能取消訂房

如果企業只賣與容量完全相同的數量，就會因為這些情況而造成空位。

因此許多公司採用 超額預訂（Overbooking）。

超額預訂是根據歷史資料，預估取消或未到場的比例，並多賣出少量票券。航空公司是最著名的例子，但飯店與活動產業也常使用這種策略。

在良好管理下，超額預訂可以提高容量利用率，同時將衝突風險控制在合理範圍內。

不只是航空業

彈性定價與超額預訂其實廣泛存在於許多產業，例如：

• 電影院

• 飯店與旅館

• 演唱會與體育賽事

• 共乘平台

• 公共交通系統

這些方法都屬於 收益管理（Revenue Management） 的核心策略。

核心原則

對於保存期限極短的產品而言，企業的目標不是單純「賣得越多越好」，而是：

在有限容量下創造最大的收益。

透過彈性定價與超額預訂，企業可以把有限的座位、房間或票券，分配給最願意付費的顧客，從而提高整體收益。

Flexible Pricing and Overbooking: Maximizing Profit for Perishable Capacity

 Flexible Pricing and Overbooking: Maximizing Profit for Perishable Capacity

Many businesses sell products that expire quickly. Airline seats, movie tickets, hotel rooms, and event seats all share a common characteristic: once the time passes, the product loses all value. An empty airplane seat after takeoff or an unsold movie ticket after the show starts cannot be stored or sold later.

This type of product is called perishable capacity.

From a management perspective, the real challenge is not simply selling everything. The true objective is maximizing profit from limited capacity.

Understanding the Real Constraint

In industries such as airlines, cinemas, hotels, and live events, the main constraint is usually fixed capacity.

• A plane has a fixed number of seats.

• A movie theater has a fixed number of seats per screening.

• A concert venue has a fixed seating capacity.

Because capacity cannot easily change in the short term, the key question becomes:

How can businesses generate the highest profit from each unit of capacity?

This is where flexible pricing and overbooking become powerful strategies.

Flexible Pricing: Selling the Same Seat at Different Prices

Not all customers value the same product equally.

For example, airline passengers often fall into different groups:

• Early planners looking for cheaper tickets

• Leisure travelers with moderate price sensitivity

• Business travelers who may pay much higher prices for last-minute flights

Similarly, movie theaters see different behaviors:

• Discount seekers attending weekday matinees

• Casual viewers choosing weekend showtimes

• Fans willing to pay premium prices on opening night

If a company sets one fixed price, it leaves money on the table.

Flexible pricing solves this by adjusting prices based on time, demand, and customer behavior. Some tickets are sold earlier at lower prices to ensure baseline demand, while other tickets are reserved for customers willing to pay more later.

This allows businesses to capture more value from the same limited capacity.

Why the Best Pricing Sometimes Leaves a Seat Unsold

At first glance, the goal might seem obvious: sell every seat.

However, if every seat always sells out quickly, it often means the price was too low. Demand exceeded capacity, which means customers were willing to pay more.

Optimal pricing usually means demand is very close to capacity, but not always perfectly equal. As a result, sometimes a seat may remain empty. Counterintuitively, this can signal that pricing is close to optimal.

Overbooking: Managing Uncertainty

Another common challenge is no-shows.

Passengers miss flights. Moviegoers change plans. Hotel guests cancel reservations. If businesses sell exactly the number of available seats or rooms, some capacity will inevitably go unused.

To address this, many companies use overbooking.

Overbooking means selling slightly more tickets than available capacity, based on historical data about cancellation or no-show rates. Airlines have long used this approach, but it also appears in other industries such as hotels and event management.

When managed carefully, overbooking helps businesses ensure that their capacity is utilized more effectively while keeping the risk of conflicts manageable.

Applications Beyond Airlines

Flexible pricing and overbooking are not limited to aviation. They are widely used in industries with perishable capacity, including:

• Movie theaters

• Hotels and resorts

• Live concerts and sports events

• Ride-sharing platforms

• Public transportation

These strategies belong to a broader discipline known as revenue management, which focuses on selling the right product, to the right customer, at the right price, at the right time.

The Core Principle

For products with short shelf life, the objective is not simply maximizing sales volume. Instead, the real goal is maximizing profit from limited capacity.

Flexible pricing and overbooking help organizations allocate their scarce capacity to customers who value it most, ensuring that every seat, room, or ticket contributes as much value as possible.

讓系統順暢與讓人忙碌之間的平衡

 

讓系統順暢與讓人忙碌之間的平衡

在任何組織中，人們常以為讓大家都忙起來，代表效率高、產能強。然而實際上，如果讓每個人都滿載運作，整個系統反而會變慢。因為當所有人都處於極限狀態，就沒有空間做調整、回應或創新。只要一個環節出錯或延誤，就可能引發整體的阻塞與壓力。

成熟的管理並不是追求所有人都忙，而是讓系統維持順暢。這往往表示有些人看起來會「閒著」，但那段閒置其實是讓系統保持彈性與回應力的緩衝。就像城市的交通，如果每條道路都塞滿車輛，整體就動不了；而適度的空間，才能讓流動順利進行。真正的效率，不是每分每秒都在做事，而是整個系統能持續穩定地往前。

The Balance Between Busyness and Flow

 

The Balance Between Busyness and Flow

In any organization, there’s a common belief that keeping everyone busy means higher productivity. But in reality, if you keep everyone fully occupied, the system starts to slow down. When every person or process is running at full capacity, there’s no room left to adjust, respond, or innovate. One small delay or mistake can ripple through the whole system, creating bottlenecks and stress.

A well-managed operation doesn’t aim for constant busyness — it aims for smooth flow. That often means some people seem “idle” at times, but that idle time is actually a buffer that keeps the system flexible and responsive. Think of it like a city’s traffic: if every road were filled to the limit, movement would stop. But with reasonable spacing, everyone gets where they’re going faster. Efficiency is not about doing more every minute; it’s about keeping the whole system moving without friction.
